Here, a viscoplastic model is built considering dislocation glide in ½{\textless}110{\textgreater}\{100\} and ½{\textless}110{\textgreater}\{110\} slip systems. The constitutive law parameters are determined adjusting the temperature dependency of the experimental critical resolved shear stress for both principal slip modes. Crystal plasticity finite element simulations of single crystal compression tests show a reasonable agreement with experimental viscoplastic anisotropy of {UO}2. However, for specific orientations where ½{\textless}110{\textgreater}\{111\} slip is observed experimentally, significant differences remain between experimental and computed compression stresses. Therefore, the role of ½{\textless}110{\textgreater}\{111\} slip is investigated based on a parametric study that provides new insights on {UO}2 plastic deformation. Several parameterizations of ½{\textless}110{\textgreater}\{111\} slip are tested highlighting the complexity of {UO}2 viscoplastic behavior. Significant improvements are still required to explain all simulation-experiment gaps.}, 7 journaltitle = {Journal of Nuclear Materials}, 8 shortjournal = {Journal of Nuclear Materials}, 9 author = {Portelette, Luc and Amodeo, Jonathan and Madec, Ronan and Soulacroix, Julian and Helfer, Thomas and Michel, Bruno}, 10 date = {2018-06-22}, 11 file = {Portelette et al. - 2018 - Crystal viscoplastic modeling of UO2 single crysta.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/F9F9GWWV/Portelette et al. - 2018 - Crystal viscoplastic modeling of UO2 single crysta.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/HW24Z59V/S0022311518305981.html:text/html} 12} 13 14@inproceedings{chetra_modecomportement_2017, 15 location = {Giens, France}, 16 title = {Modèle de comportement élastoplastique adapté à la simulation numérique du soudage}, 17 abstract = {Nous proposons un modèle de comportement élastoplastique adapté au calcul thermomécanique à haute température, rencontré par exemple en simulation numérique du soudage.

Different aspects of in-situ tests inside an {SEM} chamber have been considered. First, the characterization and corrections of bias and uncertainties of different {SEM} imaging modalities ({SE}, {BSE}, and {EBSD}) have been performed. Precise registrations of {SEM} images in different modalities have been developed in order to give a comprehensive description of the sample surface topographies. Crystallographic orientation maps (from {EBSD} analyses) are registered to measure the crystal rotation and displacement fields along the tensile test. The elastic deformations of the surface are assessed by integrated correlation of high-resolution electron diffraction images. The 3D microstructure of the analyzed sample is revealed a posteriori by combining {FIB} milling {andEBSD} images.The experimental test is also simulated by crystal plasticity calculations on a 3D mesh created according to the 3D microstructure observed in the deformed configuration. An algorithm has been proposed to estimate its initial configuration and to identify the plastic parameters iteratively. A synthetic 2D model has been used to prove its feasibility. Two crystal plasticity laws have been validated on the 3D mesh, namely dislocation dynamics for body-centered cubic crystals and a modified version of Méric-Cailletaud model.

First, a new isotropic yield criterion with threefold rotational symmetry about the origin is proposed. This criterion is an odd function in the principal values of the stress deviator. It involves only one parameter that is expressible in terms of the yield strengths in compression and tension. Comparisons with the results of polycrystalline simulations performed by Hosford and Allen [Met. Trans. 4 (1973) 1424–1425] show that the proposed macroscopic criterion describes very well the asymmetry in yielding due to activation of twinning. Further, the extension of this isotropic criterion to orthotropy is developed. The proposed anisotropic criterion is applied to the description of the plastic response of hexagonal close packed (hcp) materials. It is shown that the proposed anisotropic criterion reproduces with great accuracy both the higher strength in tension than in compression and the higher tensile strength in the transverse direction than in the rolling direction observed in textured magnesium and magnesium alloys sheets (data after Kelly and Hosford [Trans. {TMS}-{AIME} 242 (1968) 654–661]).}, 108 pages = {2027--2045}, 109 number = {11}, 110 journaltitle = {International Journal of Plasticity}, 111 shortjournal = {International Journal of Plasticity}, 112 author = {Cazacu, Oana and Barlat, Frédéric}, 113 date = {2004-11-01}, 114 keywords = {Anisotropic yielding, Generalized invariants, hcp materials, Twinning, Yielding asymmetry}, 115 file = {Cazacu et Barlat - 2004 - A criterion for description of anisotropy and yiel.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/FPESV7Z9/Cazacu et Barlat - 2004 - A criterion for description of anisotropy and yiel.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/IJ2E8CN7/S0749641904000348.html:text/html} 116} 117 118@article{chaboche_cyclic_2012, 119 title = {Cyclic inelastic constitutive equations and their impact on the fatigue life predictions}, 120 volume = {35}, 121 issn = {0749-6419}, 122 url = {http://www.sciencedirect.com/science/article/pii/S0749641912000113}, 123 doi = {10.1016/j.ijplas.2012.01.010}, 124 abstract = {Cyclic plasticity and viscoplasticity constitutive equations are revisited in the context of fatigue life analysis of components submitted to small strain amplitudes but high strain ratio.

The discrete problem is written as the minimization of a broken nonlinear elastic energy where a local reconstruction of the displacement gradient is used. Two {HHO} methods are considered: a stabilized method where the gradient is reconstructed as a tensor-valued polynomial of order k and a stabilization is added to the discrete energy functional, and an unstabilized method which reconstructs a stable higher-order gradient and circumvents the need for stabilization.

For a wide range of applications (e.g. structural steels irradiated at low homologous temperature), void growth and coalescence fracture mechanism has been shown to be still predominant. As a consequence, a comprehensive study of the effects of irradiation-induced hardening mechanisms on void growth and coalescence in irradiated materials is required. The effects of irradiation on ductile fracture mechanisms - void growth to coalescence - are assessed in this study based on model experiments. Pure copper thin tensile samples have been irradiated with protons up to 0.01 dpa. Micron-scale holes drilled through the thickness of these samples subjected to uniaxial loading conditions allow a detailed description of void growth and coalescence. In this study, experimental data show that physical mechanisms of micron-scale void growth and coalescence are similar between the unirradiated and irradiated copper. However, an acceleration of void growth is observed in the later case, resulting in earlier coalescence, which is consistent with the decrease of fracture toughness reported in irradiated materials.

In particular, a new model is presented, obtained by extending to 3D a fourth order polynomial {LITS} derivative function in a way that allows the effects of the stress confinement to be taken into account. For comparison purposes, the same fourth order polynomial {LITS} derivative function is also implemented in 3D through the classic confinement-independent modelling approach. These constitutive relationships are adopted to model transient experiments performed on concrete subjected to constant uniaxial and biaxial compressive loads. The results show that the confinement-dependent modelling approach gives a better prediction of the {LITS} state developing in the case of biaxial compression than the classic confinement-independent approach. Finally, the validated confinement-dependent model is applied to evaluate the {LITS}-related stress redistribution taking place in a typical Prestressed Concrete Pressure Vessel ({PCPV}) subjected to heating to 500 °C and cooling back to the normal operating temperature of 50 °C.

As regards the latter case of transient in particular, {ALCYONE} is intended to predictively simulate the response of a fuel rod by taking account of mechanisms in a way that models the physics as closely as possible, encompassing all possible stages of the transient as well as various fuel/cladding material types and irradiation conditions of interest. On the way to complying with these objectives, {ALCYONE} development and validation shall include tests on {PWR}-{UO}2 fuel rods with advanced claddings such as M5® under “low pressure–low temperature” or “high pressure–high temperature” water coolant conditions. This article first presents {ALCYONE} V1.4 {RIA}-related features and modeling. It especially focuses on recent developments dedicated on the one hand to nonsteady water heat and mass transport and on the other hand to the modeling of grain boundary cracking-induced fission gas release and swelling. This article then compares some simulations of {RIA} transients performed on {UO}2-M5® fuel rods in flowing sodium or stagnant water coolant conditions to the relevant experimental results gained from tests performed in either the French {CABRI} or the Japanese {NSRR} nuclear transient reactor facilities. It shows in particular to what extent {ALCYONE}—starting from base irradiation conditions it itself computes—is currently able to handle both the first stage of the transient, namely the pellet-cladding mechanical interaction phase, and the second stage of the transient, should a boiling crisis occur.

This paper presents and analyzes a line search algorithm for the return mapping problem that shows excellent improvement over a Newton–Raphson model.

The proposed approach is based on a combination of the standard Newton’s algorithm with a fictive path loading algorithm. First, a time step refinement process, associated to the Newton’s algorithm, enables us to efficiently detect the beginning of unstable crack extension. Then, a fictive path loading algorithm is performed to assess an estimation of the post instability solution. Finally, this estimated solution is used as initial guess in the standard Newton’s algorithm for the same time increment. The final converged solution satisfies both the mechanical equilibrium and the mechanical behaviour integration. This paper highlights several advantages of the proposed algorithm such as robustness, easy implementation on an existing Newton’s type solver, genericity for different unstable nonlinear physical problems. An application of this new method is presented for a smeared crack model, based on a local continuous damage formulation, devoted to the simulation of brittle nuclear fuel rupture.

New strengthening coefficient values for reactions between slip systems were determined using dislocation dynamics simulations on five representative {FCC} metals, plus germanium, and on five {BCC} transition metals for \{110\} and \{112\} slip systems at high homologous temperatures. The value of the Poisson ratio affects all the strengthening coefficients to various extents ranging from small to substantial.

This methodology extends to this class of materials the possibility to evaluate both the elastic modulus and the tensile strength with a single mechanical test, without the need for other experimental tools.}, 522 journaltitle = {Scientific Reports}, 523 shortjournal = {Sci Rep}, 524 author = {Farsi, A. and Pullen, A.

The numerical implementation is based on a standard finite element discretization and on the adaptation of an alternate minimization algorithm used in previous works. The new regularization avoids crack interpenetration and predicts asymmetric results in traction and in compression.

A simple technique is proposed to construct the level-set function in that case. Compared to recent work aiming at modeling cohesive cracks within the phase field method, our framework differs in several points: the formulation is such that interfaces are not initially damaged; no additional variables are required to describe the discontinuities at the interface and fatigue cracks can be modeled. The technique allows interaction between bulk and interface cracks, e.g. nucleation from interfaces and propagation within the matrix, and for arbitrary geometries and interactions between cracks. Several benchmarks are presented to validate the model.

Hofacker, Thermodynamically-consistent phase field models of fracture: Variational principles and multi-field fe implementations, International Journal for Numerical Methods in Engineering {DOI}:10.1002/nme.2861] on phase-field-type fracture, we propose in this paper a new variational framework for rate-independent diffusive fracture that bases on the introduction of a local history field. It contains a maximum reference energy obtained in the deformation history, which may be considered as a measure for the maximum tensile strain obtained in history. It is shown that this local variable drives the evolution of the crack phase field. The introduction of the history field provides a very transparent representation of the balance equation that governs the diffusive crack topology. In particular, it allows for the construction of a new algorithmic treatment of diffusive fracture. Here, we propose an extremely robust operator split scheme that successively updates in a typical time step the history field, the crack phase field and finally the displacement field. A regularization based on a viscous crack resistance that even enhances the robustness of the algorithm may easily be added. The proposed algorithm is considered to be the canonically simple scheme for the treatment of diffusive fracture in elastic solids.

Jacobi is the most accurate, but also the slowest method, while {QL} and Cuppen are good general purpose algorithms. The analytical algorithm outperforms the others by more than a factor of 2, but becomes inaccurate or may even fail completely if the matrix entries differ greatly in magnitude. This can mostly be circumvented by using a hybrid method, which falls back to {QL} if conditions are such that the analytical calculation might become too inaccurate.

In contrast to the models available in the literature, the new model takes into account the observed dependency of {LITS} on stress confinement. Such a dependency is introduced through a confinement coefficient which makes {LITS} directly proportional to the confinement of the stress state. Also, a new practical bilinear {LITS} model is proposed and proved to be suitable for fitting the general trend of the curves experimentally obtained for different loading conditions. The presented model is embedded in a thermoelastic material constitutive law, and then verified and validated against experiments performed on concrete specimens subjected to transient temperatures up to 250 °C under uniaxial, biaxial and triaxial compressive stress states. Once calibrated and validated, the constitutive model is used to evaluate the effects of {LITS} on the structural behavior of a Prestressed Concrete Pressure Vessel ({PCPV}) of a typical Advanced Gas cooled Reactor ({AGR}) subjected to a heating-cooling cycle simulating a temporary fault in its cooling system. The results of this study indicate that the development of {LITS} significantly influences the stress redistribution in the structure. Moreover, it is shown that in the case of {PCPVs} (and by extension similar structures) it is crucial to consider the {LITS} dependence on the stress confinement.}, 880 journaltitle = {International Journal of Solids and Structures}, 881 shortjournal = {International Journal of Solids and Structures}, 882 author = {Torelli, Giacomo and Gillie, Martin and Mandal, Parthasarathi and Tran, Van-Xuan}, 883 urldate = {2016-12-12}, 884 keywords = {Concrete, Fire, Load-induced thermal strain, Modeling, Stress confinement, Temperature, Thermal strain, Transient thermal creep}, 885 file = {ScienceDirect Full Text PDF:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/ZFC7B9B5/Torelli et al. - A multiaxial load-induced thermal strain constitut.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/2UA43NIS/S0020768316303456.html:text/html} 886} 887 888@online{cea_epx_2016, 889 title = {`Europlexus` web site}, 890 url = {http://www-epx.cea.fr/index.php/what-is-epx}, 891 author = {{CEA} and {JRC}}, 892 date = {2016} 893} 894 895@article{bary_thermoviscoelastic_2016, 896 title = {Thermoviscoelastic Analysis of Concrete Creep at Mesoscale}, 897 volume = {711}, 898 doi = {10.4028/www.scientific.net/KEM.711.652}, 899 abstract = {Concrete is a heterogeneous material made up at mesoscale of linear elastic aggregates distributed in a mortar matrix whose behavior is time and temperature dependent.

This treatment allows the dilatational stiffness to be handled separately to alleviate ill conditioning of the tangent stiffness matrix. However, this can lead to complex formulations of the material tangent moduli that can be difficult to implement or may require custom {FE} codes, thus limiting their general use. Here we present an approach, based on work by Miehe (Miehe, 1996, “Numerical Computation of Algorithmic (Consistent) Tangent Moduli in Large Strain Computational Inelasticity,” Comput. Methods Appl. Mech. Eng., 134, pp. 223–240), for an efficient numerical approximation of the tangent moduli that can be easily implemented within commercial {FE} codes. By perturbing the deformation gradient, the material tangent moduli from the Jaumann rate of the Kirchhoff stress are accurately approximated by a forward difference of the associated Kirchhoff stresses. The merit of this approach is that it produces a concise mathematical formulation that is not dependent on any particular material model. Consequently, once the approximation method is coded in a subroutine, it can be used for other hyperelastic material models with no modification. The implementation and accuracy of this approach is first demonstrated with a simple neo-Hookean material. Subsequently, a fiber-reinforced structural model is applied to analyze the pressure-diameter curve during blood vessel inflation. Implementation of this approach will facilitate the incorporation of novel hyperelastic material models for a soft tissue behavior into commercial {FE} software.}, 950 pages = {061003--061003}, 951 number = {6}, 952 journaltitle = {Journal of biomechanical engineering}, 953 eprinttype = {jstor}, 954 eprint = {{PMC}2724673}, 955 author = {Sun, Wei and Chaikof, Elliot L and Levenston, Marc E}, 956 date = {2008-12} 957} 958@article{hure_intergranular_2016, 959 title = {Intergranular stress distributions in polycrystalline aggregates of irradiated stainless steel}, 960 volume = {476}, 961 issn = {0022-3115}, 962 url = {http://www.sciencedirect.com/science/article/pii/S0022311516301313}, 963 doi = {10.1016/j.jnucmat.2016.04.017}, 964 abstract = {In order to predict {InterGranular} Stress Corrosion Cracking ({IGSCC}) of post-irradiated austenitic stainless steel in Light Water Reactor ({LWR}) environment, reliable predictions of intergranular stresses are required.

Intergranular normal stress probability density functions are found with respect to plastic strain and irradiation level, for uniaxial loading conditions. In addition, plastic slip activity jumps at grain boundaries are also presented. Intergranular normal stress distributions describe, from a statistical point of view, the potential increase of intergranular stress with respect to the macroscopic stress due to grain-grain interactions. The distributions are shown to be well described by a master curve once rescaled by the macroscopic stress, in the range of irradiation level and strain considered in this study.

La teneur en matière fissile y étant différente, ces phases évoluent différemment sous irradiation, tant du point de vue mécanique que du point de vue chimique. Pour modéliser correctement le comportement macroscopique du combustible MOX dans un code de calcul industriel, les modèles ont besoin d'être alimentés de façon pertinente en propriétés effectives, mais il est aussi intéressant de disposer d'informations sur les champs locaux afin d'établir des couplages entre les mécanismes (couplage mécanique physico-chimie). L'objectif de la thèse fut donc de développer une modélisation par changement d'échelles, basée sur l'approche NTFA (Michel et Suquet 2003). Ces développements ont été réalisés sur des microstructures tridimensionnelles (3D) représentatives du combustible MOX et pour un comportement local visco-élastique vieillissant avec déformations libres.

This case study reports on the decomposition of indium hydroxide (c-In(OH)3) to bixbyite-type indium oxide (c-In2O3). The electron beam is focused onto a single cube-shaped In(OH)3 crystal of \{100\} morphology with ca. 35 nm edge length and a sequence of HR-TEM images was recorded during electron beam irradiation. The frame-by-frame analysis of video sequences allows for the in situ, time-resolved observation of the shape and orientation of the transformed crystals, which in turn enables the evaluation of the kinetics of c-In2O3 crystallization. Supplementary material (video of the transformation) related to this article can be found online at 10.1016/j.jssc.2012.09.022. After irradiation the shape of the parent cube-shaped crystal is preserved, however, its linear dimension (edge) is reduced by the factor 1.20. The corresponding spotted selected area electron diffraction (SAED) pattern representing zone [001] of c-In(OH)3 is transformed to a diffuse strongly textured ring-like pattern of c-In2O3 that indicates the transformed cube is no longer a single crystal but is disintegrated into individual c-In2O3 domains with the size of about 5–10 nm. The induction time of approximately 15 s is estimated from the time-resolved Fourier transforms. The volume fraction of the transformed phase (c-In2O3), calculated from the shrinkage of the parent c-In(OH)3 crystal in the recorded HR-TEM images, is used as a measure of the kinetics of c-In2O3 crystallization within the framework of Avrami–Erofeev formalism. The Avrami exponent of ∼3 is characteristic for a reaction mechanism with fast nucleation at the beginning of the reaction and subsequent three-dimensional growth of nuclei with a constant growth rate. The structural transformation path in reconstructive decomposition of c-In(OH)3 to c-In2O3 is discussed in terms of (i) the displacement of hydrogen atoms that lead to breaking the hydrogen bond between OH groups of [In(OH)6] octahedra and finally to their destabilization and (ii) transformation of the vertices-shared indium–oxygen octahedra in c-In(OH)3 to vertices- and edge-shared octahedra in c-In2O3.}, 1130 number = {0}, 1131 journal = {Journal of Solid State Chemistry}, 1132 author = {Miehe, Gerhard and Lauterbach, Stefan and Kleebe, Hans-Joachim and Gurlo, Aleksander}, 1133 month = feb, 1134 year = {2013}, 1135 keywords = {Crystallographic transformation, Decomposition reaction, Indium oxide, In situ, Kinetics, Transmission electron microscopy}, 1136 pages = {364--370} 1137} 1138 1139@techreport{castelier_homogeneisation_2006, 1140 title = {Homogénéisation thermomécanique des plaques de combustible {RCG}}, 1141 number = {NT/SESC/LLCC 05-016}, 1142 institution = {DEC/SESC/LSC}, 1143 author = {Castelier, Étienne}, 1144 year = {2006} 1145} 1146 1147@article{magnier_bipotential_2014, 1148 title = {Bipotential versus return mapping algorithms: {Implementation} of non associated flow rules}, 1149 volume = {51}, 1150 issn = {0020-7683}, 1151 shorttitle = {Bipotential versus return mapping algorithms}, 1152 url = {http://www.sciencedirect.com/science/article/pii/S002076831400153X}, 1153 doi = {10.1016/j.ijsolstr.2014.04.004}, 1154 abstract = {Numerical implementation of constitutive laws involves specific incremental methods.

The smallest voids are intragranular and spherical in shape whereas the largest pores located at the grain boundary are ellipsoidal and randomly oriented. In this first part of the study, attention is focused on the effective properties of these materials with fixed microstructure. In a first step, the poro-elastic properties of these doubly voided materials are studied. Then two rigorous upper bounds are derived for the effective poro-plastic constitutive relations of these materials. The first bound, obtained by generalizing the approach of Gologanu et al. (Gologanu, M., Leblond, J., Devaux, J., 1994. Approximate models for ductile metals containing non-spherical voids-case of axisymmetric oblate ellipsoidal cavities. ASME J. Eng. Mater. Technol. 116, 290–297) to compressible materials, is accurate at high stress-triaxiality. The second one, which derives from the variational method of Ponte Castañeda (Ponte Castañeda, P., 1991. The effective mechanical properties of non-linear isotropic composites. J. Mech. Phys. Solids 39, 45–71), is accurate when the stress triaxiality is low. A N-phase model, inspired by Bilger et al. (Bilger, N., Auslender, F., Bornert, M., Masson, R., 2002. New bounds and estimates for porous media with rigid perfectly plastic matrix. C.R. Mécanique 330, 127–132), is proposed which matches the best of the two bounds at low and high triaxiality. The effect of internal pressures is discussed. In particular it is shown that when the two internal pressures coincide, the effective flow surface of the saturated biporous material is obtained from that of the drained material by a shift along the hydrostatic axis. However, when the two pressures are different, the modifications brought to the effective flow surface in the drained case involve not only a shift along the hydrostatic axis but also a change in shape and size of the surface.}, 1397 number = {3–4}, 1398 urldate = {2014-01-08}, 1399 journal = {International Journal of Solids and Structures}, 1400 author = {Vincent, Pierre-Guy and Monerie, Yann and Suquet, Pierre}, 1401 month = feb, 1402 year = {2009}, 1403 keywords = {Damage, Micromechanics, Plasticity}, 1404 pages = {480--506}, 1405 file = {ScienceDirect Full Text PDF:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/3Z28CZDC/Vincent et al. - 2009 - Porous materials with two populations of voids und.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/VM532762/Vincent et al. - 2009 - Porous materials with two populations of voids und.html:text/html} 1406} 1407 1408@techreport{marelle_alcyone_2013, 1409 type = {Note technique}, 1410 title = {Alcyone {V}1.3 : notice de présentation}, 1411 number = {13-034}, 1412 institution = {CEA/DEN/CAD/ DEC/SESC/LSC}, 1413 author = {Marelle, Vincent and Bouineau, Vincent and Bouloré, Antoine and Fillaux, Clara and Goldbronn, Patrick and Helfer, Thomas and Julien, Jérôme and Masson, Renaud and Michel, Bruno and Michel, Frédéric and Noirot, Laurence}, 1414 month = jun, 1415 year = {2013}, 1416 file = {Marelle et al. - 2013 - Alcyone V1.3 notice de présentation.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/H3SGF3UP/Marelle et al. - 2013 - Alcyone V1.3 notice de présentation.pdf:application/pdf} 1417} 1418 1419@article{liebe_aspects_2001, 1420 title = {some aspects of a gradient damage formulation}, 1421 volume = {10}, 1422 number = {n 2/3/4}, 1423 journal = {Revue Européenne des Eléments Finis}, 1424 author = {Liebe, T. and Steinmann, P. and Benallal, A.}, 1425 year = {2001}, 1426 pages = {157--172} 1427} 1428 1429@article{coplien_curiously_1995, 1430 title = {Curiously recurring template patterns}, 1431 volume = {7}, 1432 number = {2}, 1433 journal = {C++ Report}, 1434 author = {Coplien, James O}, 1435 year = {1995}, 1436 pages = {24--27} 1437} 1438 1439@techreport{edf_comportements_2013, 1440 type = {Référence du {Code} {Aster}}, 1441 title = {Comportements non linéaires}, 1442 url = {http://www.code-aster.org}, 1443 number = {U4.51.11 révision : 10568}, 1444 institution = {EDF-R\&D/AMA}, 1445 author = {EDF}, 1446 year = {2013} 1447} 1448 1449@techreport{gatt_fracturation_2004, 1450 title = {Fracturation des combustibles {UO}2 et {UO}2 dopé}, 1451 number = {(à paraître)}, 1452 institution = {SESC/LLCC}, 1453 author = {Gatt, J.

The absorber material is sintered, 10B enriched, boron carbide. The can is made of 316 type stainless steel, stabilised, or not, with titanium. The experience gained in Phenix up to now is important, and deals with about six loads of control rods. Results confirm the validity of the design of the absorber pins. Some difficulties have been encountered for the guiding devices, due to the swelling of the steel. They have required design and material improvements. Such difficulties are discarded by a new design of the bearing, for the Super-Phenix control rods. The other parts of these rods, from the Primary Shut-Down System, are strictly derived from Phenix. The design of the rods from the Secondary Shut-Down System is rather different, but it's not the case for the design of the absorber pins: in many ways, they are derived from Phenix pins and from Rapsodie control rods.

GERMINAL V2 is using a standard « 1D1⁄2 » 1538representation of the fuel pin. Thermal analysis and mechanics are now based on finite elements computations. 1539The fuel pellet is considered as a continuum, with a mechanical behaviour model managing element elimination 1540during the central hole formation. The expansion due to cracking during heat-up, and later the free volumes 1541closure between the fragments, are described by two imposed strain terms. By solving the fuel / cladding system 1542equilibrium, we intend to evaluate the mechanical interaction, which can become significant, and the stresses 1543induced by swelling gradients in the cladding thickness. Off-normal conditions are simulated by a strong 1544coupling of thermal-hydraulics in the coolant with the thermal analysis of the fuel pin. A new neutronics scheme 1545has also been developed, integrating progressively the evolutions of volatile fission products. Their release at 1546high burn-up causes the “Joint Oxyde-Gaine” formation between pellet and cladding. With a refined prediction 1547of the JOG composition, we intend to improve the evaluation of heat exchange inside gap at high burn-up, and 1548also the description of cladding corrosion. Helium production has already been completed, to simulate fuel pins 1549loaded with minor actinides. All these evolutions implemented in GERMINAL V2 are being validated by 1550simulating fuel elements irradiated in PHENIX or in CABRI reactor.

Industrial processes often use high temperature forming to fabricate components of complex shape from alloys such as aluminum or magnesium that have low room temperature formability. Accurate forming models to integrate warm forming in computer aided engineering (CAE) in production environment has been hampered by a lack of constitutive relations at elevated temperatures, forcing one to rely on experimental data for such integration. In this paper, a new thermo elasto-viscoplastic (TEV) constitutive relation is developed to model the behavior of face-centred cubic (FCC) polycrystals, especially aluminum alloys, at elevated temperatures. The model takes into account the temperature dependence of the single crystal elastic coefficients, single slip hardening parameters, thermal softening, rate sensitivity, and the total deformation. The TEV framework has been implemented into the commercial finite element code LS-DYNA to study the effects of temperature on metal forming. Uniaxial tension simulations at six different temperatures ranging from 25 °C to 260 °C have been performed and calibrated with published experimental results. Equations for the variation of single-slip hardening parameters with temperature have been developed for the AA5754 aluminum alloy. Shear test simulations at different temperatures have been used to validate the model. The proposed framework for the single slip parameters for uniaxial tension accurately predicts the shear stress-shear strain data without the need for any further fitting parameter.

In contrast to existing kinematical approaches to finite plasticity of glassy polymers, the formulation applies a plastic metric theory based on an additive split of Lagrangian Hencky-type strains into elastic and plastic parts. The analogy between the proposed formulation in the logarithmic strain space and the geometrically linear theory of plasticity, makes this constitutive framework very transparent and attractive with regard to its numerical formulation. The characteristic strain hardening of the model is derived from a polymer network model. We consider the particularly simple eight chain model, but also comment on the recently developed microsphere model. The viscoplastic flow rule in the logarithmic strain space uses structures of the free volume flow theory, which provides a highly predictive modeling capacity at the onset of viscoplastic flow. The integration of this micromechanically motivated approach into a three-dimensional computational model is a key concern of this work. We outline details of the numerical implementation of this model, including elements such as geometric pre- and post-transformations to/from the logarithmic strain space, a thermomechanical operator split algorithm consisting of an isothermal mechanical predictor followed by a heat conduction corrector and finally, the consistent linearization of the local update algorithm for the dissipative variables as well as its relationship to the global tangent operator. The performance of the proposed formulation is demonstrated by means of a spectrum of numerical examples, which we compare with our experimental findings.}, 1623 number = {13}, 1624 journal = {International Journal of Solids and Structures}, 1625 author = {Miehe, Christian and Méndez Diez, Joel and Göktepe, Serdar and Schänzel, Lisa-Marie}, 1626 month = jun, 1627 year = {2011}, 1628 keywords = {Finite thermoviscoplasticity, Glassy polymers, Logarithmic strains, Network models}, 1629 pages = {1799--1817} 1630} 1631 1632@article{fuketa_behavior_2001, 1633 title = {Behavior of high-burnup pwr fuels with low-tin zircaloy-4 cladding under reactivity-initiated-accident conditions}, 1634 volume = {133}, 1635 issn = {0029-5450}, 1636 url = {http://cat.inist.fr/?aModele=afficheN&cpsidt=871843}, 1637 language = {eng}, 1638 number = {1}, 1639 urldate = {2014-09-18}, 1640 journal = {Nuclear technology}, 1641 author = {Fuketa, Toyoshi and Sasajima, Hideo and Sugiyama, Tomoyuki}, 1642 year = {2001}, 1643 keywords = {Accident, Accident déclenché par réactivité, Accidente, Asia, Asie, Burnup, Clad, Combustible nucléaire, Combustible nuclear, Combustion nucléaire, Combustión nuclear, Corrosion, Corrosión, Estaño aleación, Estudio experimental, Etain alliage, Etude expérimentale, Experimental study, Gaine(combustible), Japan, Japon, Japón, Nuclear fuel, Nuclear reactor, Nuclear safety, Pressurized water reactor, Réacteur eau pressurisée, Réacteur nucléaire, Réacteur recherche, Reactivity initiated accident, Reactor agua a presión, Reactor investigación, Reactor nuclear, Research reactor, Seguridad nuclear, Sûreté nucléaire, Tin alloy, Vaina(combustible), Zircaloy, Zirconio aleación}, 1644 pages = {50--62}, 1645 file = {Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/7APQHACR/cat.inist.fr.html:text/html} 1646} 1647 1648@article{irons_version_1969, 1649 title = {A version of the {Aitken} accelerator for computer iteration}, 1650 volume = {1}, 1651 issn = {1097-0207}, 1652 url = {http://dx.doi.org/10.1002/nme.1620010306}, 1653 doi = {10.1002/nme.1620010306}, 1654 number = {3}, 1655 journal = {International Journal for Numerical Methods in Engineering}, 1656 author = {Irons, Bruce M. and Tuck, Robert C.}, 1657 year = {1969}, 1658 pages = {275--277} 1659} 1660 1661@techreport{helfer_ajout_2010, 1662 title = {Ajout de connaissances matériau (propriétes matériau, lois de comportement et modèles - au code {Celaeno} à l'aide générateur code {MFront}}, 1663 number = {10-002}, 1664 institution = {DEC/SESC/LSC}, 1665 author = {Helfer, Thomas and Castelier, Étienne and Bruno, Éric and Gohier, Éric and Bonhomme, Christian}, 1666 year = {2010}, 1667 file = {Helfer et al. - 2010 - Ajout de connaissances matériau (propriétes matéri.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/F6DA6FAU/Helfer et al. - 2010 - Ajout de connaissances matériau (propriétes matéri.pdf:application/pdf} 1668} 1669 1670@techreport{muller_recherche_2006, 1671 type = {rapport de stage d'option scientifique}, 1672 title = {Recherche d'une solution analytique pour le problème mécanique de la pastille combustible en \$2D{\textbackslash}left(r,þeta{\textbackslash}right)\$}, 1673 institution = {École Polytechnique}, 1674 author = {Muller, Sébastien and Helfer, Thomas and Masson, Renaud}, 1675 year = {2006} 1676} 1677 1678@article{walz_implicit_1990, 1679 title = {An implicit integration algorithm for plane stress viscoplastic constitutive equations}, 1680 volume = {36}, 1681 issn = {0045-7949}, 1682 url = {http://www.sciencedirect.com/science/article/pii/004579499090287C}, 1683 doi = {10.1016/0045-7949(90)90287-C}, 1684 abstract = {An implicit integration algorithm, the generalized midpoint rule, is applied to a set of viscoplastic constitutive equations under the plane stress constraint.

The local plastic strain field is divided into a volumetric part and a deviatoric part. Each part is expressed as a linear combination of relevant non-uniform plastic strain fields, called “plastic modes”. The non-uniform microscopic strain fields are thus described by a finite number of reduced internal variables. And the local constitutive models are then reformulated in terms of such variables. The proposed model is applied to two typical heterogeneous materials: inclusion reinforced composite and porous material. Numerical results obtained by the NTFA are compared with the direct finite element solutions. In particular, the macroscopic yield stresses of porous materials are compared between the NTFA and some recently proposed analytical criteria.

Within the framework of closest-point-projection algorithms, a methodology is presented whereby tangent operators consistent with this class of algorithms may be systematically developed. To wit, associative J2 flow rules with general nonlinear kinematic and isotropic hardening rules, as well as a class of non-associative flow rules are considered. The resulting iterative solution scheme preserves the asymptotic quadratic convergence characteristic of Newton's method, whereas use of the socalled elastoplastic tangent in conjunction with a radial return integration algorithm, a procedure often employed, results in Newton type of algorithms with suboptimal rate of convergence.

The second one describes the stress distribution in a cladding bore in front of an opening pellet crack. A linear angular variation of the pellet-clad contact pressure and a constant prescribed radial displacement are considered. The closed-form solutions are checked by comparison to independent finite element models of the pellet fragment and of the cladding. Their ability to describe non-axisymmetric displacement and stress fields during loading histories representative of base irradiation and power ramps is then demonstrated by cross-comparison with the 2D pellet fragment-cladding model of the multi-dimensional fuel performance code ALCYONE.

It enables to model slant fracture in notched tensile or cracked specimens. Nevertheless, void coalescence is not the single mechanism involved in slant fracture. That is why it is necessary to combine porous plasticity with other models. In this paper, the Coulomb fracture model and the Portevin-Le Chatelier (PLC) model (or dynamic strain aging: DSA) are formulated at the slip system scale. The Coulomb model combines the resolved normal and shear stresses for each slip plane and direction. For DSA, we postulate that each slip system has its own history of dislocation pinning and unpinning by solute atoms. The models are fully coupled in the framework of classical polycrystalline plasticity. A Reduced Texture Methodology (RTM) is used to provide the computational efficiency needed for numerical applications. The RTM approach involves a significant reduction of the number of representative crystallographic orientations. The models are applied to a notched tensile specimen taken from a 6260 aluminum alloy thin-walled extrusion. Fractographic examinations show a combination of dimples and large smooth areas on the slant fracture surface (mixed fracture). It highlights the need for combined fracture models. The PLC model gives very sharp oscillations of the macroscopic plastic strain rate, associated with moving plastic strain rate bands. It leads to a significant reduction of ductility compared to porous plasticity alone.}, 2161 urldate = {2015-04-13}, 2162 journal = {International Journal of Plasticity}, 2163 author = {Rousselier, Gilles and Quilici, Stéphane}, 2164 month = jun, 2165 year = {2015}, 2166 keywords = {A.

It is shown that for the special cases of rigid-plasticity and hypoelasticity the proposed corotational rate is identical with the Green-Naghdi rate, while the ZarembaJaumann rate yields a good approximation for moderately large strains. 2224 2225To compare our exact plastic spin formula with the constitutive assumption for the plastic spin introduced by Dafalias and others, we simplify our result for small elastic-moderate plastic strains and introduce a simplest evolution law for kinematic hardening leading to the Dafalias formula and to an exact determination of its unknown coefficient. It is also shown that contrary to statements in the literature the plastic spin is not zero for vanishing kinematic hardening. 2226 2227For isotropic-elastic material with induced plastic flow undergoing isotropic and kinematic hardening constitutive and evolution laws are proposed. Elastic and plastic Lagrangean and Eulerian logarithmic strain measures are introduced and their material time derivatives and corotational rates, respectively, are considered. Finally, the elastic-plastic tangent operator is derived. 2228 2229The presented theory is implemented in a solution algorithm and numerically applied to the simple shear problem for finite elastic-finite plastic strains as well as for sub-classes of restricted strains. The results are compared with those of the literature and with those obtained by using other corotational rates.}, 2230 number = {24}, 2231 urldate = {2014-01-06}, 2232 journal = {International Journal of Solids and Structures}, 2233 author = {Schieck, B. and Stumpf, H.}, 2234 month = dec, 2235 year = {1995}, 2236 pages = {3643--3667}, 2237 file = {Schieck et Stumpf - 1995 - The appropriate corotational rate, exact formula f.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/QXG2HF3A/Schieck et Stumpf - 1995 - The appropriate corotational rate, exact formula f.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/5S2X669M/002076839500007W.html:text/html} 2238} 2239 2240@book{wikipedia_name_2009, 2241 title = {Name mangling}, 2242 url = {http://en.wikipedia.org/wiki/Name_mangling#Name_mangling_in_C.2B.2B}, 2243 author = {Wikipédia}, 2244 year = {2009} 2245} 2246 2247@article{naghdi_critical_1990, 2248 title = {A critical review of the state of finite plasticity}, 2249 abstract = {The object of this paper is to provide a critical review of the current state of plasticity in the presence of finite deformation}, 2250 journal = {Journal of Applied Mathematics and Physics}, 2251 author = {Naghdi, P.M.}, 2252 month = may, 2253 year = {1990}, 2254 pages = {315--394}, 2255 file = {Naghdi - 1990 - A critical review of the state of finite plasticit.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/WGAP5PWV/Naghdi - 1990 - A critical review of the state of finite plasticit.pdf:application/pdf} 2256} 2257 2258@article{lorentz_variational_1999, 2259 title = {A variational formulation for nonlocal damage models}, 2260 volume = {15}, 2261 issn = {0749-6419}, 2262 url = {http://www.sciencedirect.com/science/article/pii/S0749641998000576}, 2263 doi = {10.1016/S0749-6419(98)00057-6}, 2264 abstract = {To control localization phenomena exhibited by strain softening constitutive relations, several issues have been proposed by various authors, based on spatial regularization.

Among a large variety of objective rates (actually infinitely many), how to choose suitable ones has been one of the crucial points in finite elastoplasticity. It is realized that the foregoing composite formulation of elastoplasticity should fulfil certain consistency criteria in order to avoid inconsistencies or contradictions. These criteria narrow the choice of objective rates. These authors (Bruhns and co–workers and Xiao and co–workers) have recently introduced the self–consistency criterion: in a composite formulation of elastoplasticity, the rate equation intended for characterization of elastic behaviour should be exactly integrable to deliver an elastic relation. It has been demonstrated in the work of the aforementioned authors that if a composite formulation of elastoplasticity with objective rates is required to fulfil the just–stated self–consistency criterion, as it should be, then the newly discovered logarithmic rate is the only possible choice among all objective corotational rates, including the Zaremba–Jaumann rate and the Green–Naghdi rate, etc. In the afore–mentioned result, non–corotational rates, including Oldroyd rates, Cotter–Rivlin rate and Truesdell rate, etc., are not taken into consideration in general. It is the main goal of this paper to further establish the uniqueness of the logarithmic rate among all corotational and non–corotational objective rates. Essential to the attainment of this goal is the use of the yielding–stationarity criterion: the vanishing of the stress rate implies that the yield function is stationary. It is shown that the just–stated criterion is necessary for a composite Eulerian rate formulation of finite elastoplasticity to be consistent and means that the stress rate must be a corotational rate. The main goal of this article is, thus, attained by combining the just–stated result and the established result stated before.}, 2355 number = {2000}, 2356 journal = {Proceedings of the Royal Society of London.

This is different from most of models used up to now, as they were based on the hypothesis that only the initial lack of dislocations was responsible of the strain softening behavior. A model is first developed in a simple 1D framework. Evolution of the mechanical behavior with strain rate and temperature is well reproduced by this model. Then, the 1D model is extended to a 3D mechanical model, and mechanical compressive tests on UO 2 pellets are simulated.

The pseudo-strains approach allows for reformulation of the initial viscoelastic problem as an equivalent elastic one by using a simple correspondence principle. The viscoelastic model results from a homogenization procedure in which the Mori–Tanaka scheme is applied in the Laplace–Carson space for estimating the effective linear viscoelastic bulk and shear moduli of the material. A composite made of a linear viscoelastic matrix described by a generalized Maxwell model and containing distributed spherical elastic inclusions and pores is adopted as a simplified representation of the material under consideration. One interesting feature of our approach is that exact analytical expressions for both bulk and shear moduli in the time space are derived in simple cases where a limited number of Maxwell chains are involved to describe the matrix behavior. The evolutions of the damage variable are governed by an equivalent pseudo-strain calculated from the pseudo-strains. The viscodamage model is applied to the simulation of cement paste basic creep tests available in the literature. After a proper identification of the parameters, an analysis of the results obtained with moderate creep loading reveals that the total strains evolutions are due mainly to the viscous characteristics of the material and to a lesser extent to the damage growth. The effects of the pore volume fraction of the material and of high load-levels leading to the specimen rupture on the creep response are further investigated and discussed.}, 2476 urldate = {2015-01-28}, 2477 journal = {Engineering Fracture Mechanics}, 2478 author = {Thai, Minh-Quan and Bary, Benoit and He, Qi-Chang}, 2479 month = aug, 2480 year = {2014}, 2481 keywords = {Cementitious materials, Creep, Damage, Homogenization, Linear viscoelasticity, Mori–Tanaka scheme, Viscodamage}, 2482 pages = {54--72}, 2483 file = {ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/8QCDRTRX/S0013794414001325.html:text/html;Thai et al. - 2014 - A homogenization-enriched viscodamage model for ce.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/W5KKI6KZ/Thai et al. - 2014 - A homogenization-enriched viscodamage model for ce.pdf:application/pdf} 2484} 2485 2486@book{le_saux_comportement_2008-1, 2487 title = {Comportement et rupture de gaines en {Zircaloy}-4 détendu vierges, hydrurées ou irradiées en situation accidentelle de type {RIA}}, 2488 url = {http://www.theses.fr/2008ENMP1608}, 2489 abstract = {,}, 2490 urldate = {2015-01-20}, 2491 publisher = {Paris, ENMP}, 2492 author = {Le Saux, Matthieu}, 2493 month = jan, 2494 year = {2008}, 2495 file = {Le Saux - 2008 - Comportement et rupture de gaines en Zircaloy–4 De.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/NZWI88UF/Le Saux - 2008 - Comportement et rupture de gaines en Zircaloy–4 De.pdf:application/pdf;Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/6B9MIWE4/2008ENMP1608.html:text/html} 2496} 2497 2498@phdthesis{lorentz_lois_1999, 2499 title = {lois de comportement à gradients de variables internes : constructions, formulation variationnelle et mise en oeuvre numérique}, 2500 school = {LMT-Cachan, Université Paris 6}, 2501 author = {Lorentz, Éric}, 2502 year = {1999} 2503} 2504 2505@article{bodoville_plasticity_2001, 2506 title = {Plasticity with non-linear kinematic hardening: modelling and shakedown analysis by the bipotential approach}, 2507 volume = {20}, 2508 issn = {0997-7538}, 2509 shorttitle = {Plasticity with non-linear kinematic hardening}, 2510 url = {http://www.sciencedirect.com/science/article/pii/S0997753800011098}, 2511 doi = {10.1016/S0997-7538(00)01109-8}, 2512 abstract = {The class of generalised standard materials is not relevant to model the non-associative constitutive equations.

By using different anisotropic equivalent stresses (quadratic and non-quadratic) in yield function and in plastic potential, the evolution equations for all the dissipative phenomena are deduced from the generalized normality rule applied to the plastic potential while the consistency condition is still applied to the yield function. The effect of the objective derivatives and the equivalent stresses (quadratic or non-quadratic) on the plastic flow anisotropy and the hardening evolution with damage is considered. Numerical aspects mainly related to the time integration of the fully coupled constitutive equations are discussed. Applications are made to the AISI 304 sheet metal by considering different loading paths as tensile, shear, plane tensile and bulge tests.

In contrast to the Gurson’s well known kinematical approach applied to a hollow sphere, the proposed study proceeds by means of a statical limit analysis procedure. Its development and implementation require the choice of an appropriate trial stress field. The starting point is Hill’s variational principle for rigid plastic matrix. The use of a lagrangian multiplier allows to satisfy the plastic criterion in an average sense. The proposed trial stress field, complying with internal equilibrium, is composed of an heterogeneous part (exact solution for the stress field in the hollow sphere under pure hydrostatic loading) to which is added a uniform deviatoric stress field. Owing to this choice, the stress vector conditions on the void boundary are relaxed. By solving the resulting Saddle point problem, we derive closed form formula which depends not only on the first and second invariant of the macroscopic stress tensor but also on the sign of the third invariant of the stress deviator. The obtained results are fully discussed and compared to existing models, available numerical data and to Finite Elements results obtained from cell calculation carried out during the present study. Finally, we provide for the new model the macroscopic flow rule as well as the porosity evolution equations which also show very original features.

Springer Tracts in Natural Philosophy, vol. 37) to the formulation of continua with microstructure as based upon the invariance of the internal power with respect to superimposed rigid-body rotations is extended to one based upon the Euclidean frame-indifference of the total energy balance. This is then combined with an extension of the work of Gurtin (Gurtin, M.E., 1995. Arch. Rat. Mech. Anal. 131, 67–100) on the formulation of static configurational fields to the case of dynamic and microstructure. In this way, one obtains in particular the dependence of the configurational momentum density, configurational or Eshelby stress, as well as the internal and external configurational momentum supply rate, or configurational force, densities, on the corresponding microstructural fields. These can then be used to derive the forms of the balance relations relevant to the case that the continuum contains defects at which the microstructure is discontinuous.

It focusses on the derivatives of symmetric second-order isotropic tensor functions by a symmetric second-order tensor argument. This tensor argument is assumed to be given in spectral form. The first representation explicitly needs the eigenvectors of the argument tensor and is well-known in the literature.

The evaluation of a typical model problem shows that the second representation needs less computer time than the first one.

Recent interest in the research and development of this type of methods has arisen from their capability to overcome theoretical limits of one-point methods concerning the convergence order and computational efficiency. This survey paper is a mixture of theoretical results and algorithmic aspects and it is intended as a review of the most efficient root-finding algorithms and developing techniques in a general sense. Many existing methods of great efficiency appear as special cases of presented general iterative schemes. Special attention is devoted to multipoint methods with memory that use already computed information to considerably increase convergence rate without additional computational costs. Some classical results of the 1970s which have had a great influence to the topic, often neglected or unknown to many readers, are also included not only as historical notes but also as genuine sources of many recent ideas.

An analysis of cladding strain data from experimental research reactor test programs that have simulated the RIA is presented. These data show that the cladding undergoes deformation characterized by hoop extension subject to a range of multiaxial stress states and strain paths comprised between plane-strain (no axial extension of the cladding tube) and equal-biaxial tension (equal strain in both the hoop and the axial orientations). Current mechanical test procedures of cladding material are then reviewed with a focus on their ability to generate the appropriate deformation response and to induce the prototypical multiaxial stress states and failure modes activated during a RIA. Two main groups of tests currently exist. In the first group, the deformation behavior of the cladding is examined by several variations of hoop tensile tests in which an axial contraction of the specimen gage section occurs such that a near-uniaxial tension stress state results; finite element analyses are then usually employed to deduce the deformation response, often under conditions of an assumed coefficient of friction between the specimen and test fixtures. The second group includes test procedures which attempt to reproduce the deformation and failure conditions close to those seen during a RIA such that any stress-state corrections of the failure conditions are comparatively small. The advantages and disadvantages of all of these deformation/fracture tests are discussed with special reference to testing high burnup fuel cladding.}, 3001 number = {2}, 3002 urldate = {2014-09-10}, 3003 journal = {Journal of Nuclear Materials}, 3004 author = {Desquines, J. and Koss, D.

In addition to the environmental challenges associated with surviving prolonged exposure to high temperature and corrosive media, exposure to displacive neutron irradiation pushes steels into a progressive nonequilibrium evolution involving generation of completely new microstructural components unique to the radiation environment and new phase structures driven by diffusional processes that operate only during irradiation. The result of such microstructural and microchemical alteration is often the production of an alloy that cannot be found on an equilibrium diagram. 3137 3138Concurrent with this evolution on the microscopic scale are macroscopic changes in physical and mechanical properties, and most importantly, changes in dimensional stability that are outside the realm of normal engineering experience. Such changes can strongly affect the structural integrity and limit the in-reactor lifetime of structural steels. 3139 3140While reviews of this type usually focus primarily on the displacive aspects of neutron irradiation and perhaps confine the review to one or two types of reactor, it is necessary in this review to give equal attention to the transmutation aspects of irradiation for the full range of neutron flux-spectral environments.

In the rigid plastic case, anisotropic plasticity is now reasonably well understood and is based on formulating anisotropic constitutive equations in a moving frame which, correctly chosen, will ensure objectivity and which can be postulated: (i) a priori to follow in some sense the material rotations (kinematical rotating frame); (ii) a posteriori by an appropriate constitutive evolution equation (plastic spin equation). With respect to the classical continuum models this is in fact an alternative for the formulation of frame indifferent constitutive equations. This rotating frame formulation of continuum mechanics is first formally presented and applied to anisotropic elasticity to show that in this case the proper rotating frame must be used to get a true elasticity. The remaining part of the paper is then devoted to the elastic–plastic case starting from a direct extension of the formalism with derivation of the elastic constitutive equation and plastic flow rule which is best written in the so-called isoclinic configuration. Finally the kinematic plastic rotating frames will be introduced and exemplified as the appropriate choice for a correct description of an anisotropic elastic–plastic behaviour.}, 3245 number = {52}, 3246 urldate = {2014-01-16}, 3247 journal = {International Journal of Solids and Structures}, 3248 author = {Sidoroff, F. and Dogui, A.}, 3249 month = dec, 3250 year = {2001}, 3251 keywords = {Anisotropic plasticity, Elasto-plasticity, Large deformations, Large strain}, 3252 pages = {9569--9578}, 3253 file = {ScienceDirect Full Text PDF:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/IX4K2A2U/Sidoroff and Dogui - 2001 - Some issues about anisotropic elasticplastic mode.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/BW4EHP6Q/Sidoroff and Dogui - 2001 - Some issues about anisotropic elasticplastic mode.html:text/html} 3254} 3255 3256@techreport{marelle_alcyone_2014, 3257 type = {Note technique}, 3258 title = {Alcyone {V}1.4 : notice de présentation}, 3259 number = {13-034}, 3260 institution = {CEA/DEN/CAD/ DEC/SESC/LSC}, 3261 author = {Marelle, Vincent and Bouineau, Vincent and Bouloré, Antoine and Fillaux, Clara and Goldbronn, Patrick and Helfer, Thomas and Julien, Jérôme and Masson, Renaud and Michel, Bruno and Noirot, Laurence and Ramière, Isabelle}, 3262 month = feb, 3263 year = {2014}, 3264 file = {Marelle et al. - 2014 - Alcyone V1.4 notice de présentation.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/PNC5T42W/Marelle et al. - 2014 - Alcyone V1.4 notice de présentation.pdf:application/pdf} 3265} 3266 3267@article{lassmann_transuranus:_1992, 3268 title = {{TRANSURANUS}: a fuel rod analysis code ready for use}, 3269 volume = {188}, 3270 issn = {0022-3115}, 3271 shorttitle = {{TRANSURANUS}}, 3272 url = {http://www.sciencedirect.com/science/article/pii/0022311592904876}, 3273 doi = {10.1016/0022-3115(92)90487-6}, 3274 abstract = {TRANSURANUS is a computer program for the thermal and mechanical analysis of fuel rods in nuclear reactors and was developed at the European Institute for Transuranium Elements (TUI).

Revisiting brittle fracture as an energy minimization problem. J. Mech. Phys. Solids 46 (8), 1319–1342]. We focus on the linear elastic case where the contact condition appears as a local unilateral constraint on the displacement jump at the crack surfaces. The regularized model is obtained by splitting the strain energy in a spherical and a deviatoric parts and accounting for the sign of the local volume change.

The effects of irradiation on fatigue appear to be modest except at high temperature where helium embrittlement becomes important. The swelling-independent component of irradiation creep strain increases linearly with dose and is relatively insensitive to material variables and irradiation temperature, except at low temperatures where accelerated creep may occur as a result of low vacancy mobility. Creep rupture life is a strong function of helium content, but is less sensitive to metallurgical conditions. Irradiation-induced stress corrosion cracking appears to be related to the evolution of radiation-induced segregation/depletion at grain boundaries, and hence may not be significant at low irradiation temperatures.}, 3411 number = {2–3}, 3412 urldate = {2014-01-17}, 3413 journal = {Journal of Nuclear Materials}, 3414 author = {Lucas, G.

An important experimental and research cooperative program between EDF, AREVA-NP and the Atomic Energy Commission CEA is achieved in order to get a better understanding of the mechanisms possibly leading to PCI failure, as well as to qualify a PCI resistant rod design. The objectives of this work are: first, to improve the understanding of the pellet mechanical properties impact on cladding local loading with 3D simulations results, and second, to propose a new phenomenological rupture criterion for a better assessment of the failure risk. 3558 3559In this study fuel behaviour modelling under nominal and transient loading conditions is achieved with a multi-dimensional simulation tool called ALCYONE, included in the new fuel software PLEIADES currently co-developed by the CEA and EDF. Cladding loading due to mechanical interaction during power transient stage is first analysed through pellet–cladding interfacial stresses computed in the 3D simulation. Then, a 2D model is proposed in order to establish a correlation between interfacial loading and stress concentration in the cladding. In order to assess the failure risk under PCI a phenomenological criterion based on the membrane circumferential stress in the cladding and shear stresses at pellet–cladding interface is proposed. To compute the shear loading at pellet–cladding interface a new parameter (called Wrθ) is introduced. Based on 3D calculations of PCI, it is shown in this paper that pellet fracture properties can have a significant effect on PCI loading.}, 3560 number = {7}, 3561 urldate = {2014-01-08}, 3562 journal = {Nuclear Engineering and Design}, 3563 author = {Michel, B. and Sercombe, J. and Thouvenin, G.}, 3564 month = jul, 3565 year = {2008}, 3566 pages = {1612--1628}, 3567 file = {Michel et al. - 2008 - A new phenomenological criterion for pellet–claddi.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/GTK4RE8A/Michel et al. - 2008 - A new phenomenological criterion for pellet–claddi.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/J4JWEJEJ/Michel et al. - 2008 - A new phenomenological criterion for pelletcladdi.html:text/html} 3568} 3569 3570@article{hughes_unconditionally_1978, 3571 title = {Unconditionally stable algorithms for quasi-static elasto/visco-plastic finite element analysis}, 3572 volume = {8}, 3573 issn = {0045-7949}, 3574 url = {http://www.sciencedirect.com/science/article/pii/0045794978900196}, 3575 doi = {10.1016/0045-7949(78)90019-6}, 3576 abstract = {A new one-parameter family of implicit algorithms for quasi-static elasto/visco-plastic finite element analysis is proposed.

GERMINAL V2 is using a standard « 1D1⁄2 » 3612representation of the fuel pin. Thermal analysis and mechanics are now based on finite elements computations. 3613The fuel pellet is considered as a continuum, with a mechanical behaviour model managing element elimination 3614during the central hole formation. The expansion due to cracking during heat-up, and later the free volumes 3615closure between the fragments, are described by two imposed strain terms. By solving the fuel / cladding system 3616equilibrium, we intend to evaluate the mechanical interaction, which can become significant, and the stresses 3617induced by swelling gradients in the cladding thickness. Off-normal conditions are simulated by a strong 3618coupling of thermal-hydraulics in the coolant with the thermal analysis of the fuel pin. A new neutronics scheme 3619has also been developed, integrating progressively the evolutions of volatile fission products. Their release at 3620high burn-up causes the “Joint Oxyde-Gaine” formation between pellet and cladding. With a refined prediction 3621of the JOG composition, we intend to improve the evaluation of heat exchange inside gap at high burn-up, and 3622also the description of cladding corrosion. Helium production has already been completed, to simulate fuel pins 3623loaded with minor actinides. All these evolutions implemented in GERMINAL V2 are being validated by 3624simulating fuel elements irradiated in PHENIX or in CABRI reactor. We are considering objects from different 3625geometries, with various cladding materials, burn-ups and irradiation histories.

In the algorithm, the trial stress obtained by elastic prediction is geometrically relaxed to the closest point on the yield surface in the principal stress plane. The direction of return-mapping is first obtained through the minimization problem using the Newton-Raphson method, and thereafter the plastic parameter is determined. As a model of yield criterion, Hill's quadratic normal anisotropic yield function has been adopted. The accuracy of the algorithm has been shown by iso-error maps for several materials. It has been revealed that errors are within 5\% when the explicit time-integration method is adopted. In order to show the applicability of the algorithm, two kinds of sheet metal forming processes being able to represent various states of stress on the yield surface have been analyzed by FORMSYS-DE, the in-house explicit FEM code.

Industrial processes often use high temperature forming to fabricate components of complex shape from alloys such as aluminum or magnesium that have low room temperature formability. Accurate forming models to integrate warm forming in computer aided engineering (CAE) in production environment has been hampered by a lack of constitutive relations at elevated temperatures, forcing one to rely on experimental data for such integration. In this paper, a new thermo elasto-viscoplastic (TEV) constitutive relation is developed to model the behavior of face-centred cubic (FCC) polycrystals, especially aluminum alloys, at elevated temperatures. The model takes into account the temperature dependence of the single crystal elastic coefficients, single slip hardening parameters, thermal softening, rate sensitivity, and the total deformation. The TEV framework has been implemented into the commercial finite element code LS-DYNA to study the effects of temperature on metal forming. Uniaxial tension simulations at six different temperatures ranging from 25 °C to 260 °C have been performed and calibrated with published experimental results. Equations for the variation of single-slip hardening parameters with temperature have been developed for the AA5754 aluminum alloy. Shear test simulations at different temperatures have been used to validate the model. The proposed framework for the single slip parameters for uniaxial tension accurately predicts the shear stress-shear strain data without the need for any further fitting parameter. Temperature dependence of texture evolution, single slip hardening and hardening rates, thermal softening, and slip activity in AA5754 sheet alloy during temperatures corresponding to warm forming temperatures are investigated.}, 3746 urldate = {2015-05-20}, 3747 journal = {International Journal of Plasticity}, 3748 author = {Cyr, Edward D. and Mohammadi, Mohsen and Mishra, Raja K. and Inal, Kaan}, 3749 month = jul, 3750 year = {2015}, 3751 keywords = {A.

(ii) The definition of a convex elastic domain in the space of the local stress-like variable conjugate to the plastic metric, denoted as the plastic force. (iii) An equivalent Lagrangian and Eulerian representation of all constitutive functions as isotropic tensor functions in terms of an extended set of arguments, denoted as anisotropy variables.

INTRODUCTION As of 1994, the performance of C++ for scientific computing was disappointing. Typical benchmark results showed C++ lagging behind Fortran's performance by anywhere from 20\% to a factor of ten. The performance of C++ was so poor that mixed-language programming was necessary: a program's framework could be written in C++, but any speed-critical routines had to be coded in Fortran. In the past five years there have been significant developments. There is now an optimizing C++ compiler available from Kuck and Associates (KAI C++) [4] which is able to perform C++ specific optimizations. Two new programming techniques (expression templates and template metaprograms) trick the compiler into performing optimizations such as loop fusion and algorithm specialization.

The algorithm addressed in this paper is dedicated to face-centered-cubic (FCC) crystal structures. Its first feature is a much more efficient and more accurate integration scheme of the constitutive equations compared to previous attempts. This scheme is based on a fully implicit integration procedure, yet it may be transformed easily into an explicit scheme. Determining the set of active slip systems is performed by the use of a combinatorial search procedure, and the determination of the slip rates of the different active slip systems is based on the fixed point method. The second feature of this algorithm stems from the original method used to solve the ambiguity of the possible non-uniqueness of the set of active slip systems. A robust method, based on a small positive perturbation of the critical shear stresses, is proposed to overcome this difficulty. It is worth mentioning that the algorithm developed in this paper is not limited to one particular hardening law or to FCC crystal structures. Rather, it can be used and extended to various hardening laws and crystal structures (e.g. BCC or HCP…) in a straightforward manner. The authors demonstrate the performance of the proposed algorithm and illustrate its accuracy and efficiency through various numerical simulations at the single crystal and polycrystal scales. The predicted results obtained from those simulations were compared with those obtained using other numerical techniques and algorithms (i.e., a pseudo-inversion technique and an explicit algorithm). Our numerical predictions are also compared with some numerical and experimental results from other papers. The response of the polycrystal was computed by using the proposed algorithm combined with Taylor’s homogenization scheme, which is used to compute the overall polycrystalline behavior. The paper ends with a statistical study of the influence of the perturbation technique on the response prediction for a single crystal and a polycrystal.}, 4219 urldate = {2014-01-16}, 4220 journal = {International Journal of Plasticity}, 4221 author = {Ben Bettaieb, Mohamed and Débordes, Olivier and Dogui, Abdelwaheb and Duchêne, Laurent and Keller, Clément}, 4222 month = may, 4223 year = {2012}, 4224 keywords = {FCC single crystal, Finite strain, Non-linear hardening, Numerical integration, Schmid’s law}, 4225 pages = {184--217}, 4226 file = {Ben Bettaieb et al. - 2012 - On the numerical integration of rate independent s.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/M5GSZTJ9/Ben Bettaieb et al. - 2012 - On the numerical integration of rate independent s.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/KU2XD494/S074964191100180X.html:text/html} 4227} 4228 4229@article{fremond_damage_1996, 4230 title = {damage, gradient of damage and principle of virtual power}, 4231 volume = {33}, 4232 number = {8}, 4233 journal = {International Journal of Solids and Structures}, 4234 author = {Frémond, M. and Nedjar, B.}, 4235 month = mar, 4236 year = {1996}, 4237 pages = {1083--1103} 4238} 4239 4240@techreport{helfer_proposition_2005, 4241 title = {Proposition d'un modèle d'endommagement pour la modélisation 3D du réseau de fissures secondaire apparaissant dans la pastille combustible - {Implantation} dans {Cast}3M}, 4242 institution = {DEC/SESC/LLCC}, 4243 author = {Helfer, Thomas}, 4244 month = nov, 4245 year = {2005} 4246} 4247 4248@inproceedings{blanc_characterization_2015, 4249 address = {Manchester UK}, 4250 title = {Characterization, {Simulation} and {Improvement} of {Spacer} {Pads} {Mechanical} {Behaviour} for {Sodium} {Fast} {Reactor} {Fuel} {Subassemblies}}, 4251 author = {Blanc, Victor and Jeanningros, Xavier and Helfer, Thomas and Lamagnère, Pierre and Beck, Thierry}, 4252 month = aug, 4253 year = {2015} 4254} 4255 4256@article{tvergaard_effect_1990, 4257 title = {effect of fibre debonding in a whisker reinforced metal}, 4258 volume = {A125}, 4259 journal = {Mater.

This multiphysics behavior is often tightly coupled and many important aspects are inherently multidimensional. Most current fuel modeling codes employ loose multiphysics coupling and are restricted to 2D axisymmetric or 1.5D approximations. This paper describes a new modeling tool able to simulate coupled multiphysics and multiscale fuel behavior, for either 2D axisymmetric or 3D geometries. Specific fuel analysis capabilities currently implemented in this tool are described, followed by a set of demonstration problems which include a 10-pellet light water reactor fuel rodlet, three-dimensional analysis of pellet clad mechanical interaction in the vicinity of a defective fuel pellet, coupled heat transfer and fission product diffusion in a TRISO-coated fuel particle, a demonstration of the ability to couple to lower-length scale models to account for material property variation with microstructural evolution, and a demonstration of the tool’s ability to efficiently solve very large and complex problems using massively-parallel computing.

The formulation is suitable for the simulation of carbon-black filled rubbers in monotonic and cyclic deformation processes under isothermal conditions. The underlying key approach is an experimentally motivated a priori decomposition of the local stress response into three constitutive branches which act in parallel: a rubber–elastic ground–stress response, a rate-dependent viscoelastic overstress response and a rate-independent plastoelastic overstress response. The damage is assumed to act isotropically on all three branches. These three branches are represented in a completely analogous format within separate eigenvalue spaces, where we apply a recently proposed compact setting of finite inelasticity based on developing reference metric tensors. On the numerical side, we propose a time integration scheme which exploits intrinsically the modular structure of the proposed constitutive model. This is achieved on the basis of a convenient operator split of the local evolution system, which we decouple into a stress evolution problem and a parameter evolution problem. The constitutive functions involved in the proposed model are specified for a particular filled rubber on the basis of a parameter identification process. The paper concludes with some numerical examples which demonstrate the overall response of the proposed model by means of a representative set of numerical examples.}, 4363 number = {2}, 4364 journal = {Journal of the Mechanics and Physics of Solids}, 4365 author = {Miehe, Christian and Keck, Joachim}, 4366 month = feb, 4367 year = {2000}, 4368 keywords = {A.

The theory is based on the additive decomposition of the logarithmic strain tensor. The stress conjugate to the logarithmic strain then plays the role of the thermodynamically driving force. The approach in this paper is motivated by the search for numerically accessible structures which can be extended to incorporate anisotropy as well. Specifically in this region, multiplicative formulations become extremely tedious. The evolution equations are of the unified type due to Bodner and Partom, and are modified so as to fit into the theoretical framework adopted. The numerical treatment of the problem is fully developed. Specifically, the algorithmic aspects of the approach are discussed and various applications to shell problems are considered. A shell theory with seven degrees of freedom, together with a four-node enhanced strain finite element formulation, is used. A central feature of the shell formulation is its eligibility to the application of a three-dimensional constitutive law.}, 4387 number = {15}, 4388 urldate = {2015-04-23}, 4389 journal = {Computers \& Structures}, 4390 author = {Sansour, Carlo and Wagner, Werner}, 4391 month = jul, 4392 year = {2003}, 4393 keywords = {Algorithmic strain, Finite elements, Shell theory, Viscoplasticity}, 4394 pages = {1583--1594}, 4395 file = {ScienceDirect Full Text PDF:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/HFJE4QD4/Sansour et Wagner - 2003 - Viscoplasticity based on additive decomposition of.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/I4DKVXBX/S0045794903001494.html:text/html} 4396} 4397 4398@inproceedings{plancq_pleiades_2004, 4399 address = {Florida}, 4400 title = {{PLEIADES} : a unified environment for multi-dimensional fuel performance modeling}, 4401 booktitle = {International meeting on {LWR} fuel performance}, 4402 author = {Plancq, David and Thouvenin, Gilles and Ricaud, Jean-Marc and Struzik, Christine and Helfer, Thomas and Bentejac, Frédéric and Thévenin, Philippe and Masson, Renaud}, 4403 year = {2004} 4404} 4405 4406@techreport{edf_mfront03_2014, 4407 type = {Référence du {Code} {Aster}}, 4408 title = {{MFRONT}03 – {Test} de l'interface {Code}\_Aster-{MFRONT} pour des lois avec orthotropie}, 4409 url = {http://www.code-aster.org}, 4410 number = {V1.03.128}, 4411 institution = {EDF-R\&D/AMA}, 4412 author = {EDF}, 4413 month = apr, 4414 year = {2014} 4415} 4416 4417@article{bretelle_formulation_2000, 4418 title = {Formulation du contact avec adhérence en élasticité non linéaire entre deux solides déformables}, 4419 volume = {Tome 328}, 4420 journal = {C.

L'objectif de cette thèse est de poursuivre et d’étendre les 4515travaux de la thèse de Xu Han (2009-2012) avec pour finalité de proposer une modélisation de l’effet des 4516cavités à l'échelle cristalline sur les propriétés mécaniques et notamment sur l’évolution de la ténacité des 4517structures Internes. Les résultats obtenus lors de la première année de thèse sont : 4518i. 4519ii. 4520iii. 4521Les lois de plasticité cristallines proposées par Xu Han pour décrire le comportement en fonction 4522de la dose ont été implémentées en petites déformations et en grandes transformations dans le 4523générateur de lois de comportement Mfront utilisable à terme dans Cast3m, dans Code\_Aster 4524(EDF) et dans le code Zset (Mines Paristech). Les tests de traction sur l’implémentation dans 4525Mfront ont été réalisés en comparaison avec les mêmes tests dans le code Z-set. Un bon accord 4526entre les deux codes a été observé avec le jeu de paramètres simplifiés (matrice d’interaction 4527entre systèmes de glissement homogène) validant l’implémentation dans Mfront. L’utilisation 4528d’une matrice d’interaction non-homogène telle que déterminée à partir des calculs de dynamique 4529de dislocations révèle de faibles écarts pour certaines directions cristallographiques lorsque le 4530comportement montre une phase d’adoucissement (état irradié). L’origine de ces écarts en en 4531cours d’étude. 4532Le formalisme en grandes transformations du modèle monocristallin homogénéisé poreux 4533proposé dans la thèse de Xu Han a été explicité et est présenté dans son intégralité dans ce 4534rapport. 4535L’extension du modèle d’homogénéisation monocristallin poreux à la description de la croissance 4536des cavités a été étudiée. Le caractère prédictif du modèle monocristallin poreux tel que proposé 4537par Xu Han a été étudié en comparant les comportements de référence (obtenus par calculs sur 4538la cellule poreuse) et à la réponse obtenue sur élément de volume. A partir des 456 calculs sur 4539cellule, il est mis en évidence un bon accord entre les vitesses de croissance obtenues par le 4540modèle homogénéisé et les calculs de référence pour un grand nombre de cas (orientation 4541cristallographique, porosité, triaxialité). Cependant, plusieurs cas ont été identifiés où la vitesse 4542de croissance de cavité est surestimée par le modèle homogénéisé. Des écarts significatifs sont 4543obtenus principalement pour des triaxialités entre 1/3 et 2. Afin d’étudier l’origine de ces écarts, 4544des équations analytiques ont été développées sous certaines hypothèses permettant d’obtenir la 4545solution exacte de la vitesse de croissance des cavités. Pour ces conditions particulières, il est 4546ainsi montré que les résultats du modèle homogénéisé obtenus par la simulation sont en accord 4547avec le calcul analytique, mais que ces résultats ne sont pas en accord avec ceux des calculs de 4548référence sur cellule poreuse. Deux phénomènes ont été identifiés comme cause possible des 4549écarts observés dans les calculs sur cellule poreuse (localisation de la déformation et bifurcation 4550numérique) et sont actuellement en cours d’étude. Par ailleurs, pour les très fortes triaxialités 4551({\textgreater}20), un écart entre les surfaces de charge effectives du modèle homogénéisé et celle issue du 4552calcul de référence a été identifié, mais ces niveaux de triaxialité ne sont pas d’intérêt pour notre 4553étude. 4554La deuxième de la thèse sera consacrée à : (i) la poursuite de l’étude du modèle homogénéisé 4555particulièrement pour la phase de coalescence, (ii) la prise en compte de l’effet de taille des cavités 4556en proposant un formalisme de plasticité à gradient qui sera intégré au modèle homogénéisé, (iii) 4557l’évaluation du comportement mécanique d’éprouvette de traction en présence d’une fissure.}, 4558 number = {DEN/DANS/DMN/SEMI/LCMI/2015-008/A}, 4559 institution = {CEA DEN/DANS/DMN/SEMI/LCMI}, 4560 author = {Ling, Chao}, 4561 month = mar, 4562 year = {2015}, 4563 pages = {74}, 4564 file = {Ling - 2015 - Modélisation de la rupture ductile des internes de.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/XR33WA38/Ling - 2015 - Modélisation de la rupture ductile des internes de.pdf:application/pdf} 4565} 4566 4567@article{hj_matzke_surface_1980, 4568 title = {the surface energy of $_{\textrm{2}}$ as determined by hertzian indentation}, 4569 volume = {91}, 4570 journal = {Journal of Nuclear Materials}, 4571 author = {Hj Matzke, T.

After this first stage, the increase of cladding temperature can lead to the Departure from Nucleate Boiling. During the film boiling regime, the clad temperature can reach a very high temperature (\>700 °C).

The theoretical frame is the well-established continuum slip theory based on the multiplicative decomposition of the deformation gradient into elastic and plastic parts. A key feature of the present paper is the introduction and computational exploitation of a particularly simple hyperelastic stress response function based on a further multiplicative decomposition of the elastic deformation gradient into spherical and unimodular parts, resulting in a very convenient representation of the Schmid resolved shear stresses on the crystallographic slip systems in terms of a simple inner product of Eulerian vectors. This observation is intrinsically exploited on the numerical side by formulating a new fully implicit stress update algorithm and the associated consistent elastoplastic moduli in terms of these Eulerian vectors. The proposed return mapping algorithm treats the possibly redundant constraints of large-strain multisurface plasticity for single crystals by means of an active set search.

In view of the strong interactions between the various aspects of fuel performance and the resulting mathematical problems, the simulation of the fuel behavior requires fuel performance codes, which are being used by safety authorities, research organizations, and fuel vendors.

The variational formulation allows for general dissipative solids, including finite elastic and plastic deformations, non-Newtonian viscosity, rate sensitivity, arbitrary flow and hardening rules, as well as heat conduction. We show that a joint potential function exists such that both the conservation of energy and the balance of linear momentum equations follow as Euler–Lagrange equations. The identification of the joint potential requires a careful distinction between equilibrium and external temperatures, which are equal at equilibrium.

The formulation is developed using hyperelasticity in terms of logarithmic strains, the multiplicative decomposition of the deformation gradient into an elastic and a plastic part, and the exponential mapping. The novelty in the computational procedure is that it retains the conceptual simplicity of the large strain isotropic elasto-plastic algorithms based on the same ingredients. The plastic correction is performed using a standard small strain procedure in which the stresses are interpreted as generalized Kirchhoff stresses and the strains as logarithmic strains, and the large strain kinematics is reduced to a geometric pre- and post-processor. The procedure is independent of the specified yield function and type of hardening used, and for isotropic elasticity, the algorithm of Eterović and Bathe is automatically recovered as a special case.

On the shell theory side, we consider several possible continuum based parametrizations of the shell deformation and investigate their applicability with respect to the implementation of general three-dimensional local constitutive models. As an aspect of computational shell analysis we then discuss in detail the numerical implementation of a shell based on the parametrization of the top and bottom surface in terms of a new 8-node brick-type mixed finite shell element on the basis of assumed strain and enhanced strain variational approaches. On the side of plasticity theory we adopt a recently proposed intermediate-configuration-free formulation of large-strain plasticity based on the notion of a plastic metric and consider its representation with respect to the parameter manifold of the shell. This frame is formulated in terms of principal strains and principal stresses with respect to dual co- and contra-variant eigenvector triads associated with a mixed-variant elastic strain tensor. The new aspect of computational plasticity is the development of a stress update algorithm for the plasticity model mentioned above which includes a general return mapping in the eigenvalue space. The algorithm can be applied to general coordinate charts and is particularly convenient when formulated with respect to the space of the curvilinear coordinates of the shell parametrization.

That consists first in defining the total energy which contains, in particular, a gradient damage term and a term which represents the plastic dissipation but depends also on damage. Then, the evolution law is deduced from the principles of irreversibility, stability and energy balance. Accordingly, the plastic dissipation term which appears both in the damage criterion and the plastic yield criterion plays an essential role in the damage–plasticity coupling. Suitable constitutive choices on how the plastic yield stress decreases with damage, allows us to obtain a rich variety of coupled responses. A particular attention is paid on the equations which govern the formation of cohesive cracks where the displacement is discontinuous and the plasticity localizes. In the one-dimensional traction test where the solution is obtained in a closed form, we show that, because of damage localization, a cohesive crack really appears at the center of the damage zone before the rupture and the associated cohesive law is obtained in closed form in terms of the constitutive parameters. A Finite Element discrete version of the energy functional is used to simulate a two-dimensional traction test over a rectangular domain with mixed boundary conditions; again a localized band of plastic strain is generated seemingly independent of the mesh size.}, 5252 urldate = {2014-09-30}, 5253 journal = {Mechanics of Materials}, 5254 author = {Alessi, Roberto and Marigo, Jean-Jacques and Vidoli, Stefano}, 5255 keywords = {Cohesive crack, Ductile fracture, Gradient damage model, Plasticity, Variational approach}, 5256 file = {Alessi et al. - Gradient damage models coupled with plasticity Va.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/4JSD3TD4/Alessi et al. - Gradient damage models coupled with plasticity Va.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/NR2PHDT7/S0167663614000039.html:text/html} 5257} 5258 5259@techreport{helfer_specification_2007, 5260 type = {Note interne}, 5261 title = {Spécification du code généré par la base de données de propriétés physique {\textbackslash}sirius}, 5262 institution = {DEC/SESC/LSC}, 5263 author = {Helfer, T. and Bouhamou, N. and Bonhomme, C.}, 5264 year = {2007} 5265} 5266 5267@book{stroustrup_langage_2004, 5268 address = {Paris}, 5269 title = {Le langage {C}++}, 5270 isbn = {2744070033 9782744070037}, 5271 language = {French}, 5272 publisher = {Pearson Education}, 5273 author = {Stroustrup, Bjarne and Eberhardt, Christine}, 5274 year = {2004} 5275} 5276 5277@article{lorentz_gradient_2005-1, 5278 title = {Gradient constitutive relations: numerical aspects and application to gradient damage}, 5279 volume = {194}, 5280 issn = {0045-7825}, 5281 shorttitle = {Gradient constitutive relations}, 5282 url = {http://www.sciencedirect.com/science/article/pii/S0045782505000307}, 5283 doi = {10.1016/j.cma.2004.12.016}, 5284 abstract = {The description of localisation and structural failure through local strain-softening constitutive laws leads to ill-posed problems.

On the theoretical side, a Eulerian setting of isotropic thermoelasticity is discussed, based on the Finger tensor as a strain measure. Novel aspects are a direct representation of the Eulerian thermoelastic moduli in terms of the Finger tensor and a rigorous decomposition of the thermoelastic response functions into decoupled volumetric and isochoric contributions based on a multiplicative split of the Finger tensor into spherical and unimodular parts. An algorithmic procedure for the computation of the stress and thermoelastic moduli, based on a representation of the free energy in terms of eigenvalues of the unimodular part of the Finger tensor, is developed and applied to model problems of strictly entropic and modified entropic thermoelasticity. Furthermore, two algorithms for the solution of the coupled problem are discussed, based on operator splits of the global field equations of thermoelasticity.

The proposed concept is applied to the simulation of texture evolution in polycrystalline metals, where the micro-structure consists of a representative assembly of single crystal grains. The deformation of this micro-structure is coupled with the local deformation at a typical material point of the macro-continuum by three alternative constraints of the microscopic fluctuation field. In a deformation driven process, extensive macroscopic variables, like stresses and dissipation are defined as volume averages of their microscopic counterparts in an accompanying local equilibrium state of the micro-structure. The proposed numerical implementation is based in the general setting on a finite element discretization of the macro-continuum which is locally coupled at each Gauss point with a finite element discretization of the attached micro-structure. In the first part of the paper we set up the two coupled boundary value problems associated with the macro-continuum and the pointwise attached micro-structure and consider aspects of their finite element solutions. The second part presents details of a robust algorithmic model of finite plasticity for single crystals which governs the response of the grains in a typical micro-structure. The paper concludes with some representative numerical examples by demonstrating the performance of the proposed concept with regard to the prediction of texture evolution in polycrystals.}, 5591 number = {3–4}, 5592 journal = {Computer Methods in Applied Mechanics and Engineering}, 5593 author = {Miehe, Christian and Schröder, Jörg and Schotte, Jan}, 5594 month = apr, 5595 year = {1999}, 5596 pages = {387--418} 5597} 5598 5599@article{palmer_growth_1973, 5600 title = {the growth of slip surfaces in the progressive failure of over-consolidated clay}, 5601 volume = {A. 322}, 5602 journal = {Proc.

Jusqu'à présent, beaucoup efforts ont été contribués pour identifier les effets d'irradiation sur l'évolution microstructurale du matériau (dislocations, boucles de Frank, cavités, ségrégation, etc.). Le gonflement induit par irradiation, considéré comme un facteur limitant la durée de fonctionnement des réacteurs, pourrait modifier les propriétés mécaniques des matériaux (plasticité, ténacité, etc), même conduire à une distorsion des structures du fait des modifications dimensionnelles entre les différentes composantes.L'objectif principal de ce travail de thèse est d'étudier qualitativement l'influence de l'effet du gonflement sur le comportement mécanique des matériaux irradiés. Un modèle micromécanique constitutif en grandes déformations basé sur les évolutions de la densité de dislocations et de défauts d'irradiation (boucles de Frank) est développé et implémenté dans les codes de calcul éléments finis ZéBuLoN et Cast3M. Les simulations numériques sont réalisées pour calculer les propriétés mécaniques d'un agrégat polycristallin. Par ailleurs, la technique d'homogénéisation est appliquée pour développer un modèle de type Gurson. Les simulations d'une cellule poreuse sont utilisés pour étudier le comportement mécanique des monocristaux poreux, en tenant compte des différents effets de la triaxialité, de la porosité et de l'orientation cristallographique, afin d'étudier l'effet de la présence des cavités sur la plasticité et la rugosité du matériau irradié à l'échelle polycristallin.}, 5678 school = {Ecole Doctorale Sciences des Métiers de l'Ingénieur}, 5679 author = {Han, Xu}, 5680 year = {2012}, 5681 file = {Han - 2012 - Modélisation de la fragilisation due au gonflement.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/SWVMPRQZ/Han - 2012 - Modélisation de la fragilisation due au gonflement.pdf:application/pdf} 5682} 5683 5684@article{foerch_polymorphic_1997, 5685 title = {Polymorphic constitutive equations in finite element codes}, 5686 volume = {141}, 5687 issn = {0045-7825}, 5688 url = {http://www.sciencedirect.com/science/article/pii/S0045782596011115}, 5689 doi = {10.1016/S0045-7825(96)01111-5}, 5690 abstract = {This work presents an object-oriented design approach to the programming of finite element constitutive equations.

A new fuel software (PLEIADES) is currently co-developed by the Atomic Energy Commission (CEA) and Electricité de France (EDF). This software includes a multi-dimensional FE program (ALCYONE) devoted to Pressure Water Reactors (PWR) fuel rods. PCI studies are mainly undertaken with the 3D model of ALCYONE. The objectives of this work are twofold: first, to propose a constitutive model for the fuel pellet which accounts for the stress relaxation of the material resulting from cracking and creep, second, to estimate the impact of the pellet cracking on PCI. 5818 5819In this paper, a mathematical formulation which couples a viscoplastic law for creep with a multi-surface plastic softening law for cracking is detailed, leading a two inelastic strains model.

The proposed model originates from micromechanically motivated diffusion processes of the highly mobile polymer chains described within the formalism of Brownian motion. Following the basic assumption of accounting for the elastic and the viscous effects in rubber viscoelasticity by their representation through a separate elastic ground network and several viscous subnetworks, respectively, the kinetic theory of rubber elasticity is followed and extended to represent also the viscous contribution in this work. It is assumed that the stretch probability of certain chain segments within an individual viscous subnetwork evolves based on the movement of the chain endpoints described by the Smoluchowski equation extended in this work from non-interacting point particles in a viscous surrounding to flexible polymer chains. An equivalent tensorial representation for this evolution is chosen which allows for the closed form solution of the macroscopic free energy and the macroscopic viscous overstress based on a homogenization over the probability space of the introduced micro-objects. The resulting model of the viscous subnetwork is subsequently combined with the non-affine micro-sphere model and applied in homogeneous and non-homogeneous tests.

In bcc crystals, the mobility of dislocations strongly depends on temperature and dislocation line characters. Unlike the classical picture of the Orowan mechanism, simulations show that the difference in mobility between screw and non-screw characters is the key parameter. Simulations at different temperatures and with different precipitate microstructures illustrate the contribution of two mechanisms to Orowan strengthening: a thermally activated mechanism induced by the length dependency of the screw dislocation mobility and an athermal mechanism associated with dislocation line tension. The influence of the particle distribution is studied with a comparison between regular and random particle arrangements. In most cases, distribution effect can be accounted for by calculating effective particle spacing in the screw dislocation directions.}, 6130 number = {2}, 6131 urldate = {2014-05-07}, 6132 journal = {Acta Materialia}, 6133 author = {Monnet, G. and Naamane, S. and Devincre, B.}, 6134 month = jan, 6135 year = {2011}, 6136 keywords = {Bainitic steels, Carbides, Dislocation dynamics, Low temperature deformation, Thermally activated processes}, 6137 pages = {451--461}, 6138 file = {Monnet et al. - 2011 - Orowan strengthening at low temperatures in bcc ma.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/EEEFD3HG/Monnet et al. - 2011 - Orowan strengthening at low temperatures in bcc ma.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/FFMKH2MV/S1359645410006166.html:text/html} 6139} 6140 6141@inproceedings{leary_progress_1977, 6142 title = {Progress in modeling carbide and nitride fuel performance in advanced {LMFBRs}}, 6143 language = {en}, 6144 booktitle = {Advanced {LMFBR} {Fuels}: {Topical} {Meeting} {Proceedings}, {Tucson}, {Arizona}, {October} 10-13, 1977}, 6145 publisher = {American Nuclear Society}, 6146 author = {Billone, MC.}, 6147 editor = {Leary, Joseph and Kittle, Howard}, 6148 year = {1977} 6149} 6150 6151@article{berveiller_extension_1978, 6152 title = {An extension of the self-consistent scheme to plastically-flowing polycrystals}, 6153 volume = {26}, 6154 issn = {0022-5096}, 6155 url = {http://www.sciencedirect.com/science/article/pii/0022509678900030}, 6156 doi = {10.1016/0022-5096(78)90003-0}, 6157 abstract = {The general formulation of the self-consistent scheme is specified for an isotropic elasto-plastic approximation of the “constraint” tensor.

This model is applied to uniaxial tension tests for fee polycrystals. Both plastic flow and texture development are investigated. Internal stresses are shown to be significantly lowered with respect to the Kröner model predictions, due to the occurrence of plastic stress relaxation.

By treating the spatial dependent interaction between dislocations and irradiation-induced stacking fault tetrahedrons (SFTs) as a tensorial form and taking into account the influence of dislocation source limitation at submicron (∼100 nm to ∼1 μm), a unified size-dependent tensorial plasticity model for irradiated single crystals is developed. The feasibility and accuracy of this model are well validated by comparing numerical results with corresponding experimental data. It is found that (1) the yield strength of unirradiated FCC copper increases with the decrease of crystal size, which mainly attributed to the mechanism shifting from dislocation forest strengthening to dislocation source limitation strengthening. (2) For large crystal copper, the yield strength increases with the amount of irradiation, which is attributed to the increase of irradiation-induced SFTs and enhancement of dislocation–defect interaction. The phenomenon of yield dropping is observed when the irradiation is strong. (3) The competition between the irradiation effect and size effect induces the existence of a critical crystal size. Below the critical size, the yield hardening is controlled by size effect. Otherwise, it is controlled by irradiation effect. Furthermore, the proposed model can easily predict this critical crystal size, which may provide a quick guideline to distinguish different hardening mechanisms regarding different crystal sizes.}, 6199 urldate = {2015-04-13}, 6200 journal = {International Journal of Plasticity}, 6201 author = {Xiao, Xiazi and Song, Dingkun and Xue, Jianming and Chu, Haijian and Duan, Huiling}, 6202 month = feb, 6203 year = {2015}, 6204 keywords = {Constitutive behavior, Crystal plasticity, Dislocations, Irradiation effect}, 6205 pages = {152--167}, 6206 file = {ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/CDG6UXS8/S0749641914001880.html:text/html} 6207} 6208 6209@techreport{struzik_test_2005-1, 6210 title = {test des lois de fluage d'irradiation des gaines recommandées par le {SRMA} dans les conditions des {REP}}, 6211 number = {À paraître}, 6212 institution = {CEA DEN/DEC/SESC/LSC}, 6213 author = {Struzik, C. and Agard, M.}, 6214 year = {2005} 6215} 6216 6217@misc{pakin_comprehensive_2008, 6218 title = {The {Comprehensive} {LaTeX} {Symbol} {List}}, 6219 abstract = {This document lists 4947 symbols and the corresponding LaTeX commands that produce them.

While the first order theory gives very good results for small strains below approximately 5\%, simulating large strains implies numerical instabilities evidenced by the violation of the volume balances. To this purpose, an extension of the algorithm used in TRANSURANUS was proposed and verified adopting different solution methods: an analytic solution and finite element calculations by means of COMSOL. In particular, creep calculations were carried out applying a Norton law that defines cladding creep strains under varying stress conditions. The verification against the numerical solution given by COMSOL and the analytic solution shows an excellent agreement of the radial profiles of stresses and strains. 6296 6297The new code was applied to the simulation of cladding ballooning tests, and to an integral LOCA test of the FUMEX-III project.

As many thermomechanical solvers are used within the platform, one of the PLEAIADES’s main challenge is to propose a unified software environment for capitalisation of material knowledge coming from research and development programs on various nuclear systems. 6487 6488This paper introduces a tool called mfront which is basically a code generator based on C++ (Stroustrup and Eberhardt, 2004). Domain specific languages are provided which were designed to simplify the implementations of new material properties, mechanical behaviours and simple material models. mfront was recently released under the GPL open-source licence and is available on its web site: http://tfel.sourceforge.net/. 6489 6490The authors hope that it will prove useful for researchers and engineers, in particular in the field of solid mechanics. mfront interfaces generate code specific to each solver and language considered. 6491 6492In this paper, after a general overview of mfront functionalities, a particular focus is made on mechanical behaviours which are by essence more complex and may have significant impact on the numerical performances of mechanical simulations. mfront users can describe all kinds of mechanical phenomena, such as viscoplasticity, plasticity and damage, for various types of mechanical behaviour (small strain or finite strain behaviour, cohesive zone models). Performance benchmarks, performed using the Code\_Aster finite element solver, show that the code generated using mfront is in most cases on par or better than the behaviour implementations written in fortran natively available in this solver. The material knowledge management strategy that was set up within the PLEIADES platform is briefly discussed. A material database named sirius proposes a rigorous material verification workflow. 6493 6494We illustrate the use of mfront through two case of studies: a simple FFC single crystal viscoplastic behaviour and the implementation of a recent behaviour for the fuel material which describes various phenomena: fuel cracking, plasticity and viscoplasticity.}, 6495 year = 2015, 6496 urldate = {2015-07-23}, 6497 journal = {Computers \& Mathematics with Applications}, 6498 author = {Helfer, Thomas and Michel, Bruno and Proix, Jean-Michel and Salvo, Maxime and Sercombe, Jérôme and Casella, Michel}, 6499 keywords = {Domain specific languages, Implicit integration schemes, Material knowledge management, Mechanical behaviour integration, Single crystal plasticity}, 6500} 6501 6502@article{marchal_finite_2009, 6503 title = {Finite element simulation of {Pellet}-{Cladding} {Interaction} ({PCI}) in nuclear fuel rods}, 6504 volume = {45}, 6505 issn = {0927-0256}, 6506 url = {http://www.sciencedirect.com/science/article/pii/S0927025608004679}, 6507 doi = {10.1016/j.commatsci.2008.10.015}, 6508 abstract = {This paper deals with the use of the finite element method to simulate locally the phenomenon of Pellet-Cladding Interaction (PCI) in nuclear fuel rods.

This software specifically focuses on studying fast transients such as reactivity-initiated accidents (RIA) caused by possible ejection of control rods. The code aims at improving the global understanding of the physical mechanisms governing the thermal-mechanical behaviour of a single rod. It is currently used to analyse integral tests performed in CABRI and NSRR experimental reactors. The resulting validated code is used to carry out studies required to evaluate margins in relation to criteria for different types of fuel rods used in nuclear power plants. 6771 6772Because phenomena occurring during fast power transients are complex, the simulation in SCANAIR is based on a close coupling between several modules aimed at modelling thermal, thermal-hydraulics, mechanical and gas behaviour. During the first stage of fast power transients, clad deformation is mainly governed by the pellet–clad mechanical interaction (PCMI). At the later stage, heat transfers from pellet to clad bring the cladding material to such high temperatures that the boiling crisis might occurs. The significant over-pressurisation of the rod and the fact of maintaining the cladding material at elevated temperatures during a fairly long period can lead to ballooning and possible clad failure. 6773 6774A brief introduction describes the context, the historical background and recalls the main phenomena involved under fast transient conditions. Then, the main features of the SCANAIR computer code (version 7) are presented. The present paper is particularly focused on the detailed description of the thermal dynamics, the structural mechanics until the prediction of the clad failure and the gas behaviour modellings. A further paper will be focused on the code validation.}, 6775 urldate = {2014-12-04}, 6776 journal = {Nuclear Engineering and Design}, 6777 author = {Moal, Alain and Georgenthum, Vincent and Marchand, Olivier}, 6778 month = dec, 6779 year = {2014}, 6780 pages = {150--171}, 6781 file = {ScienceDirect Full Text PDF:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/7NHKSU8T/Moal et al. - 2014 - SCANAIR A transient fuel performance code Part O.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/DGAUQTQ3/S002954931400257X.html:text/html} 6782} 6783 6784@techreport{portier_influence_2004, 6785 address = {Saclay}, 6786 type = {Note technique}, 6787 title = {Influence de l’hydrogène sur le comportement métallurgique et thermomécanique de l’alliage {M}5 en conditions {APRP}}, 6788 abstract = {Afin d’étudier l’influence de l’hydruration sur la déformation et la rupture en 6789conditions accidentelles et d’aider ainsi à la modélisation du comportement en APRP des gaines 6790fortement irradiées, un programme expérimental a été réalisé depuis ces 5 dernières années sur 6791l’alliage M5 pré-hydruré.

Pour répondre à ce besoin croissant et indispensable, il existe différentes ressources exploitables comme les énergies fossiles (pétrole, charbon, gaz…), les énergies renouvelables (solaire, éolien, hydraulique…) ou l’énergie nucléaire. Ces ressources possèdent chacune des forces et des faiblesses et sont au cœur d’enjeux environnementaux majeurs. 6823En France, l’énergie nucléaire occupe une place prédominante avec ses 58 réacteurs et assure près de 80 \% de la production d’électricité du pays. Un 59ème réacteur est en construction à Flamanville avec une capacité de puissance de 1600 MW, suffisante pour alimenter une ville comme Paris. 6824Le CEA participe activement à l’évolution des technologies pour l’énergie et développe notamment de nouvelles générations de réacteurs nucléaires, améliorant les performances, la durabilité, la sûreté et l’économie de ces systèmes. C’est dans ce contexte qu’est né le projet de concevoir le réacteur rapide refroidi au sodium ASTRID.

Le travail présenté dans la suite de ce rapport concerne l’étude thermomécanique de dispositifs de commande et d’arrêt innovants, envisagés pour le réacteur ASTRID, en modifiant la structure géométrique et les matériaux neutrophages des assemblages actuels, dans le but d’améliorer leurs performances. 6827 6828Dans un premier temps, nous donnons une rapide description du contexte et des éléments nécessaires à la compréhension du sujet.

Establishing these code systems required a tremendous amount of work relating to the mathematical/mechanical description to be done, and it seems that the standard of analytical modelling enables us to understand most of the intrinsic physical fuel rod phenomena. 6928 6929Nevertheless, comparisons of theory and experiment or comparisons between several codes often show rather poor results. Moreover the interaction of complex material behavior and complex structural analysis makes it very difficult to identify the real sources of discrepancies. In most cases a few experiments with very specific objectives were used to calibrate the codes against experiments. But in general a limited data base can be understood quite satisfactorily even by contradictory models and, consequently, wide scattering results if models are applied to new situations. 6930 6931In the present paper the basic structure of fuel element codes is discussed. The concept common to all fuel element structural analyses led to a general program structure which is presented in detail. The mechanical concepts of integral fuel element codes are reviewed, with special emphasis put on the modeling of pellet/cladding interaction and axial coupling. An attempt is made to classify material data and models, and the state of the art of accident analysis by means of fuel element codes is outlined. 6932 6933The objective of this contribution is a completion of code ranking already carried out in the past.

On the thermomechanical side, novel aspects of the proposed model of thermoplasticity are (1) the explicit characterization of the plastic (configurational) entropy as an independent internal variable, (2) a thermomechanical extension of the principle of maximum dissipation consistent with the multiplicative decomposition of the deformation gradient, and (3) the exploitation of this extended principle in the formulation of an associative flow which characterizes the evolution of the plastic entropy in terms of the change of the flow criterion with respect to temperature. On the numerical analysis side, salient features of the proposed approach are (4) a new global product formula algorithm constructed via an operator split of the nonlinear initial value problem, which leads to a two-step solution procedure, (5) a unified class of local return mapping algorithms which preserves exactly the incompressibility constraint on the plastic flow and reduces to the classical radial return method for isothermal J2-flow theory, and (6) the formulation of a mixed finite element method in terms of the elastic entropy and the temperature field which circumvents well-known difficulties associated with the incompressibility constraint on the plastic flow. The exact linearization of both the product formula algorithm and an alternative simulataneous solution scheme for the coupled thermomechanical problem is given in two appendices.}, 7058 number = {1}, 7059 journal = {Computer Methods in Applied Mechanics and Engineering}, 7060 author = {Simo, J.C. and Miehe, C.}, 7061 month = jul, 7062 year = {1992}, 7063 pages = {41--104}, 7064 file = {Simo_miehe.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/CFKEJGPF/Simo_miehe.pdf:application/pdf} 7065} 7066 7067@book{francois_comportement_1995, 7068 address = {Paris}, 7069 title = {Comportement mécanique des matériaux {II} - viscoplasticité, endommagement, mécanique de la rupture, mécanique du contact}, 7070 publisher = {Hermès}, 7071 author = {François, Dominique and Pineau, André and Zaoui, André}, 7072 year = {1995} 7073} 7074 7075@book{zebulon_z-set_2000-1, 7076 title = {Z-set {Examples} {Manual}}, 7077 author = {Zebulon}, 7078 year = {2000} 7079} 7080 7081@techreport{bejaoui_irradiation_2010, 7082 title = {Irradiation {Expérimentale} {DIAMINO}, dossier de présentation}, 7083 number = {DEC/SESC/LC2I/10-006}, 7084 institution = {CEA DEN/DEC/SESC/LC2I}, 7085 author = {Bejaoui, Syriac and Lambert, Thierry}, 7086 year = {2010} 7087} 7088 7089@techreport{escleine_aiguille_2008, 7090 title = {L'aiguille "absorbante" des cøeurs rapides français : un point sur la conception, la modélisation et les moyens de calcul, perspectives}, 7091 number = {08-008}, 7092 institution = {CEA DEN/DEC/SESC/LLCC}, 7093 author = {Escleine, J.M.}, 7094 year = {2008} 7095} 7096 7097@book{simo_computational_1998, 7098 address = {New York}, 7099 title = {Computational inelasticity}, 7100 isbn = {0387975209 9780387975207}, 7101 language = {English}, 7102 publisher = {Springer}, 7103 author = {Simo, Juan C and Hughes, Thomas J.

The micromechanical model is based on an extension of the NTFA method proposed by Michel and Suquet (2003, 2004). The local plastic strain field is divided into a volumetric part and a deviatoric part. Each part is expressed as a linear combination of relevant non-uniform plastic strain fields, called “plastic modes”. The non-uniform microscopic strain fields are thus described by a finite number of reduced internal variables. And the local constitutive models are then reformulated in terms of such variables. The proposed model is applied to two typical heterogeneous materials: inclusion reinforced composite and porous material. Numerical results obtained by the NTFA are compared with the direct finite element solutions. In particular, the macroscopic yield stresses of porous materials are compared between the NTFA and some recently proposed analytical criteria. Finally, as an application example, the micromechanical model is used to simulate laboratory tests performed on porous sandstone.}, 7131 urldate = {2015-04-21}, 7132 journal = {European Journal of Mechanics - A/Solids}, 7133 author = {Jiang, T. and Shao, J.

It is being carried out under the premise that void coalescence results not only in accelerated damage development (e.g., Needleman and Tvergaard, 1984), but also in damage delocalisation (i.e., via interaction between neighbouring Gurson RVE's). To this end, we proceed by analogy with the approach of Needleman and Tvergaard (1984) who replaced the Gurson void volume fraction f with a (local) effective damage parameter f∗ in the Gurson yield condition to account for the effect of void coalescence on the material behaviour. In the current case, the role of f∗ is taken over and generalised by an effective continuum damage field ν. A field relation for ν is formulated here in the framework of continuum thermodynamics. In the simplest case, the resulting relation is formally analogous to the inhomogeneous temperature equation in which void nucleation and growth represent (local) sources for ν and in which void coalescence takes place in a process zone whose dimension is determined by a characteristic material lengthscale. Analogous to temperature, then, ν represents an additional continuum degree-of-freedom here, resulting in a coupled deformation-damage field model. In the last part of the work, the complete model for coupled damage-deformation is implemented numerically using the finite-element method on the basis of backward-Euler integration and consistent linearisation. Using this implementation, the behaviour of the current extended Gurson-based damage model is investigated for the case of simple tension of an inhomogeneous steel block. In particular, the corresponding simulation results document quantitatively the dependence of the delocalisation of the model damage process and minimisation of mesh-dependence on the characteristic dimension of the damage process zone.}, 7283 number = {6}, 7284 urldate = {2015-05-04}, 7285 journal = {European Journal of Mechanics - A/Solids}, 7286 author = {Reusch, Frederick and Svendsen, Bob and Klingbeil, Dietmar}, 7287 month = nov, 7288 year = {2003}, 7289 keywords = {Gurson-based damage modelling, Non-local modelling, Thermodynamic formulation}, 7290 pages = {779--792}, 7291 file = {Reusch et al. - 2003 - Local and non-local Gurson-based ductile damage an.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/7FQ6Q8JW/Reusch et al. - 2003 - Local and non-local Gurson-based ductile damage an.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/797XEIAB/S0997753803000706.html:text/html} 7292} 7293 7294@phdthesis{blanc_modelisation_2009, 7295 title = {Modélisation du comportement thermomécanique des combustibles à particules par une approche multi-échelle}, 7296 school = {Université de Provence}, 7297 author = {Blanc, V.}, 7298 year = {2009} 7299} 7300 7301@techreport{peterson_crack_1981, 7302 title = {Crack growth and development of fracture zones in plain concrete and similar materials}, 7303 institution = {Division of Building Materials - Lund Institute of Technology}, 7304 author = {Peterson, P.

The key ingredients on the theoretical side are the introduction of a plastic metric for the description of the local history-dependent inelastic material response, the definition of a convex elastic domain in the space of the local stress-like variable conjugate to the plastic metric, denoted as the plastic force, and a fully equivalent Lagrangian and Eulerian representation of all constitutive functions in spectral form for general non-Cartesian coordinate charts in terms of dual co- and contra-variant eigenvector triads which are normalized with respect to the plastic metric. On the numerical side, we propose a stress update algorithm for general non-associative isotropic elasto(visco)plastic response with an arbitrary number of scalar internal variables. The algorithm is based on an exponential map integrator and is recast into a general return mapping scheme, methodically organized with tensorial pre- and postprocessing and a constitutive box in the eigenvalue space. Furthermore, we propose a new perturbation stabilization technique which dramatically enhances the convergence of the general return algorithm.

The approach accounts for micro-mechanically based features of both the elastic bulk response as well as the crack toughness of idealized polymer networks. The proposed diffusive crack modeling based on the introduction of a crack phase field overcomes difficulties associated with the computational realization of sharp crack discontinuities, in particular when it comes to complex crack topologies. The crack phase field governs a crack density function, which describes the macroscopic crack surface in the polymer per unit of the reference volume. It provides the basis for the constitutive modeling of a degrading free energy storage and a crack threshold function with a Griffith-type critical energy release rate, that governs the crack propagation in the polymer. Both the energy storage as well as the critical energy release due to fracture can be related to classical statistical network theories of polymers. The proposed framework of diffusive fracture in polymers is formulated in terms of a rate-type variational principle that determines the evolution of the coupled primary variable fields, i.e. the deformation field and the crack phase field. On the computational side, we outline a staggered solution procedure based on a one-pass operator split of the coupled equations, that successively updates in a typical time step the crack phase field and the displacement field. Such a solution algorithm is extremely robust, easy to implement and ideally suited for engineering problems. We finally demonstrate the performance of the phase field formulation of fracture at large strains by means of representative numerical examples.}, 7569 number = {0}, 7570 journal = {Journal of the Mechanics and Physics of Solids}, 7571 author = {Miehe, Christian and Schänzel, Lisa-Marie}, 7572 keywords = {Coupled multi-field problem, Finite strain, Fracture, Phase field modeling, Rubbery polymers} 7573} 7574 7575@phdthesis{helfer_etude_2006, 7576 title = {Étude de l'impact de la fissuration des combustibles nucléaires oxyde sur le comportement normal et incidentel des crayons combustible}, 7577 abstract = {Le travail de thèse porte sur la fissuration des pastilles combustible UO2 des réacteurs à eau pressurisée, et ses conséquences sur le comporte ment mécanique du crayon combustible.

As such additional dimensions are incorporated into a constitutive model, it becomes progressively more complex and challenging to fit uniquely without invoking unrealistic numbers of fitting attempts starting from myriad sets of trial parameters. For 8-parameter constitutive equations similar to the ones investigated here, the literature reports fitting with 28 (256) starting sets of trial parameters, requiring 256 nonlinear optimizations using special programming, thus making such procedures impractical for many applications. An efficient, effective method requiring only 3 optimizations was proposed, developed, and confirmed for a diverse range of AHSS: DP590, DP780, DP980, TRIP780, CP1180 and TWIP. These alloys represent a wide range of hardening mechanisms, tensile elongations (0.05 to 0.5) and tensile strengths (590 to 1180 MPa). All results were derived from standard tensile tests, yet the extrapolated stresses of the constitutive models fit with the new method were confirmed independently within approximately 1\% standard deviation by balanced-biaxial bulge experiments at strains up to 6 times larger than the tensile range used to generate the constitutive models. Such accuracy at large strains is crucial for predicting the “shear fracture” of AHSS in practice.

It allows a systematic exploration of the properties of these models.

It appears that only few approaches bring effective regularisation. Unfortunately, they do not rely on thermodynamic bases so that the Clausius–Duhem inequality is not automatically fulfilled. An alternative consists in giving up the assumptions of the analysis. In that case, it seems that no general result can be stated.

This hydrogen, combined with 7875the volatile radioactive materials, leaked out of the 7876containment vessels and entered into the reactor 7877buildings, resulting in explosions. In the past, stainless 7878steel was utilized as cladding in many pressurized water 7879reactors (PWRs), and its performance under irradiation 7880was excellent. However, stainless steel was replaced by 7881zirconium-based alloy as cladding material mainly due to 7882its lower neutron absorption cross section.

Les caractérisations par métallographie, nanodureté, DRX et ERDA ont montré qu'un blister est constitué d'hydrures delta dont la concentration dans la matrice varie entre 80\% et 100\%, et que la matrice sous-jacente contient des hydrures radiaux.

Notre étude sur le comportement dilatométrique du zirconium hydruré montre le rôle important de la texture cristallographique du matériau, ce qui peut expliquer des différences de morphologie des blisters. En parallèle, des essais suivis par caméra infrarouge ont montré que des vitesses de déformation supérieures à 0,1/s induisent des échauffements locaux importants qui favorisent la localisation précoce de la déformation.

After some limited extension, the crack becomes slanted and propagates under local mixed mode I/III. Modeling and understanding this phenomenon is challenging. In this work, the “computational cell” methodology proposed in [1], which uses a predefined crack path, is used to study flat to slant fracture transition. The energy dissipation rate is studied as a function of the assumed crack tilt angle. It is shown that a minimum is always reached for an angle equal to 45°. This correlates well with the variation of the crack tip opening angle (CTOA) or the mean plastic deformation along the crack path. Stress and strain states in the stable tearing region hardly depend on the assumed tilt angle. A parametric study shows that flat to slant fracture transition is less likely to occur in materials having high work hardening and favored if additional damage is caused by the local stress/strain state (plane strain, low Lode parameter) in the stable tearing region.}, 7944 urldate = {2015-07-15}, 7945 journal = {Engineering Fracture Mechanics}, 7946 author = {Besson, J. and McCowan, C.

The approach models a rubber-like material based on a micro-structure that can be symbolized by a micro-sphere where the surface represents a continuous distribution of chain orientations in space. Core of the model is a new two-dimensional constitutive setting of the micro-mechanical response of a single polymer chain in a constrained environment defined by two micro-kinematic variables: the stretch of the chain and the contraction of the cross section of a micro-tube that contains the chain. The second key feature is a new non-affine micro-to-macro transition that defines the three-dimensional overall response of the polymer network based on a characteristic homogenization procedure of micro-variables defined on the micro-sphere of space orientations. It determines a stretch fluctuation field on the micro-sphere by a principle of minimum averaged free energy and links the two micro-kinematic variables in a non-affine format to the line-stretch and the area-stretch of the macro-continuum. Hence, the new model describes two superimposed contributions resulting from free chain motions and their topological constraints in an attractive dual geometric structure on both the micro- and the macro-level. Averaging operations on the micro-sphere are directly evaluated by an efficient numerical integration scheme. The overall model contains five effective material parameters obtained from the single chain statistics and properties of the network with clearly identifiable relationships to characteristic phenomena observed in stress–strain experiments. The approach advances features of the affine full network and the eight chain models by a substantial improvement of their modeling capacity. The excellent predictive performance is illustrated by comparative studies with previously developed network models and by fitting of various available experimental data of homogeneous and non-homogeneous tests.}, 7961 number = {11}, 7962 journal = {Journal of the Mechanics and Physics of Solids}, 7963 author = {Miehe, C. and Göktepe, S. and Lulei, F.}, 7964 month = nov, 7965 year = {2004}, 7966 keywords = {Experiments, Micromechanics, Network models, Rubber elasticity, Simulations}, 7967 pages = {2617--2660} 7968} 7969 7970@article{hjiaj_materiaux_2000, 7971 title = {Matériaux viscoplastiques et lois de normalité implicites}, 7972 volume = {328}, 7973 issn = {1620-7742}, 7974 url = {http://www.sciencedirect.com/science/article/pii/S1620774200000076}, 7975 doi = {10.1016/S1620-7742(00)00007-6}, 7976 abstract = {Résumé 7977Un certain nombre de matériaux auxquels l'ingénieur est confronté en pratique ne s'intègrent pas dans le cadre des matériaux standard généralisés (MSG) pour lesquels des algorithmes performants existent.

Par exemple, le comportement des métaux sous chargement cyclique est correctement décrit à l'aide de lois (visco-)plastiques non standard. Les bonnes propriétés des MSG découlent de la loi de normalité et de la convexité du pseudo-potentiel associé. Le concept de bi-potentiel, introduit par de Saxcé, généralise celui de pseudo-potentiel et permet d'écrire les lois d'évolution de certains matériaux non standard sous la forme de lois de normalité implicites. Ces matériaux appartiennent à la classe des matériaux standard implicites (MSI), dont la classe des MSG est un sous-ensemble.

Typical examples are constitutive laws of geomaterials. Nevertheless, they are not the only ones. For instance, laws describing the behaviour of metals under cyclic loading which are accurately approached by non standard (visco-)plastic laws. The good properties of GSM result from the generalized normality rule and the convexity of the associated pseudo-potential. The concept of bi-potential, introduced by de Saxcé, extends the notion of pseudo-potential and enables to write the evolution laws as implicit normality rules. These materials belong to the implicit standard material (ISM) class, of which the GSM class is a subset.

The yield stress was found to increase with strain rate and to decrease with temperature. Macroscopic cracking of the samples was apparent after the tests at 1100 °C. Scanning Electron Microscopy (SEM) image analyses revealed a pronounced grain boundary cracking in the core of the samples tested at 10 - 1 /s and at 1550–1700 °C. A hyperbolic sine model for the viscoplastic strain rate with a clear dependency on porosity was first developed. It was completed by a Drucker–Prager yield criterion with associated plastic flow to account for the porosity increase induced by grain boundary cracking. Finite Elements simulations of the compression tests on the dense UO2 were then successfully compared to the stress–strain curves, post-test diameter profiles and porosities at the pellets’ center, periphery and top extremity. The response of the grain boundary cracking model was then studied in biaxial compression, this condition being closer to that of the pellet during a RIA power transient.}, 8123 urldate = {2015-07-21}, 8124 journal = {Journal of Nuclear Materials}, 8125 author = {Salvo, Maxime and Sercombe, Jérôme and Helfer, Thomas and Sornay, Philippe and Désoyer, Thierry}, 8126 month = may, 8127 year = {2015}, 8128 pages = {184--199}, 8129 file = {ScienceDirect Full Text PDF:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/SMDCKH3H/Salvo et al. - 2015 - Experimental characterization and modeling of UO2 .pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/2V4XVX7C/S0022311515001130.html:text/html} 8130} 8131 8132@inproceedings{jarvi_concept-controlled_2003, 8133 title = {Concept-{Controlled} {Polymorphism}}, 8134 abstract = {Concepts -- sets of abstractions related by common requirements -- have a central role in generic programming.

Second, concepts can be used to provide fine-grained control of function and operator overloading. Finally, generic functions can be overloaded (specialized) based on concepts, rather than simply on types.

This paper focuses on the verification of the high temperature sheath creep analysis of the code. Comparisons between FAXMOD predictions using a specific creep law and out-reactor transient tube burst data demonstrate the code's capability to model high temperature creep behaviour within experimental accuracy.

It is of practical importance to be able to predict when and in what amount different phases precipitate in the material. This study is part of a larger project aiming at constructing thermodynamic models for the development of the microstructure during isothermal heat treatment and creep. This work concerns the microstructural evolution during isothermal heat treatment of an austenitic stainless steel using atom probe field ion microscopy (APFIM), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). The investigated material was niobium-stabilised steel of type AISI 347 with the major chemical composition of 0.05C-18Cr-l lNi-0.8Nb-1.6Mn (wt\%). The steel was solution annealed at for 1100°C 3 min to obtain a homogeneous and well defined starting condition and test samples were heat treated at 500–700°C for up to 70000 h.

A new fuel software (PLEIADES) is currently co-developed by the Atomic Energy Commission (CEA) and Electricité de France (EDF). This software includes a multi-dimensional FE program (ALCYONE) devoted to Pressure Water Reactors (PWR) fuel rods. PCI studies are mainly undertaken with the 3D model of ALCYONE. The objectives of this work are twofold: first, to propose a constitutive model for the fuel pellet which accounts for the stress relaxation of the material resulting from cracking and creep, second, to estimate the impact of the pellet cracking on PCI. 8397 8398In this paper, a mathematical formulation which couples a viscoplastic law for creep with a multi-surface plastic softening law for cracking is detailed, leading a two inelastic strains model. Mesh dependency is overcome thanks to a material parameter related to the finite element size. The 3D calculations of PCI presented in this paper show that the considered modelling of fuel cracking is consistent with the experimental knowledge available on crack development under irradiation. A parametric study is then presented which leads to the conclusion that the tangential stresses at the pellet cladding interface and hence the risk of PCI failure are significantly reduced when the fuel tensile strength is divided by two.}, 8399 number = {11}, 8400 urldate = {2015-05-06}, 8401 journal = {Engineering Fracture Mechanics}, 8402 author = {Michel, B. and Sercombe, J. and Thouvenin, G. and Chatelet, R.}, 8403 month = jul, 8404 year = {2008}, 8405 keywords = {Failure behaviour, Pellet–cladding interaction (PCI), PWR}, 8406 pages = {3581--3598}, 8407 file = {Michel et al. - 2008 - 3D fuel cracking modelling in pellet cladding mech.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/95BZWSXR/Michel et al. - 2008 - 3D fuel cracking modelling in pellet cladding mech.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/24AER4BA/S0013794406004759.html:text/html} 8408} 8409 8410@article{lubarda_constitutive_2004, 8411 title = {Constitutive theories based on the multiplicative decomposition of deformation gradient: {Thermoelasticity}, elastoplasticity, and biomechanics}, 8412 volume = {57}, 8413 issn = {0003-6900}, 8414 url = {http://dx.doi.org/10.1115/1.1591000}, 8415 doi = {10.1115/1.1591000}, 8416 abstract = {Some fundamental issues in the formulation of constitutive theories of material response based on the multiplicative decomposition of the deformation gradient are reviewed, with focus on finite deformation thermoelasticity, elastoplasticity, and biomechanics.

The modular kinematic setting consists of a constitutive model in the logarithmic strain space that is framed by a purely geometric pre- and postprocessing. On the theoretical side, the point of departure is an a priori six-dimensional approach to finite plasticity based on the notion of a plastic metric. In a first step, a geometric preprocessor defines a total and a plastic logarithmic strain measure obtained from the current and the plastic metrics, respectively. In a second step, these strains enter in an additive format a constitutive model of anisotropic plasticity that may have a structure identical to the geometrically linear theory. The model defines the stresses and consistent tangents work-conjugate to the logarithmic strain measure. In a third step these objects of the logarithmic space are then mapped back to nominal, Lagrangian or Eulerian objects by a geometric postprocessor. This geometric three-step-approach defines a broad class of anisotropic models of finite plasticity directly related to counterparts of the geometrically linear theory. It is specified to a model problem of anisotropic metal plasticity. On the computational side we develop an incremental variational formulation of the above outlined constitutive structure where a quasi-hyperelastic stress potential is obtained from a local constitutive minimization problem with respect to the internal variables. It is shown that this minimization problem is exclusively restricted to the logarithmic strain space in a structure identical to the small-strain theory. The minimization problem determines the internal state of the material for finite increments of time. We develop a discrete formulation in terms of just one scalar parameter for the amount of incremental flow. The existence of the incremental stress potential provides a natural basis for the definition of the geometric postprocessor based on function evaluations. Furthermore, the global initial-boundary-value-problem of the elastic–plastic solid appears in the incremental setting as an energy minimization problem. Numerical examples show that the results obtained are surprisingly close to those obtained by a reference framework of multiplicative plasticity.}, 8552 number = {47–48}, 8553 journal = {Computer Methods in Applied Mechanics and Engineering}, 8554 author = {Miehe, C. and Apel, N. and Lambrecht, M.}, 8555 month = nov, 8556 year = {2002}, 8557 keywords = {Anisotropy, Finite plasticity, Logarithmic strains, Variational formulations}, 8558 pages = {5383--5425}, 8559 file = {Miehe et al. - 2002 - Anisotropic additive plasticity in the logarithmic.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/UI789EQ6/Miehe et al. - 2002 - Anisotropic additive plasticity in the logarithmic.pdf:application/pdf} 8560} 8561 8562@techreport{edf_mfront02_2014, 8563 type = {Référence du {Code} {Aster}}, 8564 title = {{MFRONT}02 – {Test} de l'interface {Code}\_Aster-{MFRONT} avec des lois d'endommagement}, 8565 url = {http://www.code-aster.org}, 8566 number = {V1.03.127}, 8567 institution = {EDF-R\&D/AMA}, 8568 author = {EDF}, 8569 month = apr, 8570 year = {2014} 8571} 8572 8573@misc{_wiley:_????, 8574 title = {Wiley: {Nonlinear} {Finite} {Elements} for {Continua} and {Structures}, 2nd {Edition} - {Ted} {Belytschko}, {Wing} {Kam} {Liu}, {Brian} {Moran}, et al}, 8575 shorttitle = {Wiley}, 8576 url = {http://eu.wiley.com/WileyCDA/WileyTitle/productCd-1118632702.html}, 8577 urldate = {2015-05-05}, 8578 file = {Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/ZJHQPIXK/productCd-1118632702.html:text/html} 8579} 8580 8581@book{landau_physique_1982, 8582 title = {physique théorique, tome 1 : mécanique}, 8583 publisher = {Éditions Mir}, 8584 author = {Landau, L. and Lifchitz, E.}, 8585 year = {1982} 8586} 8587 8588@article{simo_unified_1985, 8589 title = {A unified approach to finite deformation elastoplastic analysis based on the use of hyperelastic constitutive equations}, 8590 volume = {49}, 8591 issn = {0045-7825}, 8592 url = {http://www.sciencedirect.com/science/article/pii/0045782585900611}, 8593 doi = {10.1016/0045-7825(85)90061-1}, 8594 abstract = {By assuming from the outset hyperelastic constitutive behavior, an alternative approach to finite deformation plasticity and viscoplasticity is proposed whereby the need for integration of spatial rate constitutive equations is entirely bypassed.

These failures are considered to result from thermal fatigue processes induced by fluctuations in a zone where stratified temperature layers occurred, the fluctuations being associated with variations in moderator flow. 8612 8613The first section evaluates the possibility of cracking due to thermal fatigue phenomena and concludes that under service conditions a crack may initiate and grow through 7 mm thickness of the branch pipe. In laboratory thermal fatigue tests that simulated the thermomechanical conditions for such a component, the number of cycles required to initiate a thermal fatigue crack in a notched modified standard fatigue specimen was about 103. This value may be used to give a conservative prediction of the number of thermal cycles for crack initiation in actual branch pipes, including those subject to the cold plug condition which is produced in some emergency shut-down and valve testing situations. 8614 8615It was also demonstrated that beyond a crack depth of 7 mm stress corrosion cracking is the main process in further crack propagation.

The first optimization, named HB-EDC for High-Biaxiality EDC, allowed to reach transverse plane strain conditions. The second optimization, named VHB-EDC for Very High Biaxiality EDC, was designed to reach higher loading biaxiality ratios. These optimized EDC tests were performed at 25 °C, 350 °C and 480 °C on unirradiated hydrided Cold Worked Stress Relieved (CWSR) Zircaloy-4 samples. First, samples unhydrided or uniformly hydrided up to 1130 wppm were tested. Second, samples hydrided at 310 wppm with a hydride blister were tested. A large ductility reduction is induced by the increase in biaxiality level in the absence of a hydride blister or with small blisters ( \< 50 μ m deep). The fracture strain decreases quickly with the blister depth at 25 °C, but more progressively at higher temperature. An equation that quantifies the fracture strain reduction with the blister depth is proposed. Eventually, one of the tests developed in the present study, the HB-EDC test, was proven to be a good compromise between the test complexity and the stress state reached.

These account for dislocation transport and curvature-induced line-length production and have been derived from a higher-dimensional continuum dislocation theory.

The particles are assumed to act as obstacles to dislocation motion, leading to pile-ups forming at the matrix–inclusion interface.

We present a unified approach for expressing high performance numerical linear algebra routines for large classes of dense and sparse matrices. As with the Standard Template Library [10], we explicitly separate algorithms from data structures through the use of generic programming techniques. We conclude that such an approach does not hinder high performance. On the contrary, writing portable high performance codes is actually enabled with such an approach because the performance critical code sections can be isolated from the algorithms and the data structures. We also tackle the performance portability problem for particular architecture dependent algorithms such as matrix-matrix multiply. Recently, code generation systems (PHiPAC [3] and ATLAS [15]) have been created to customize the algorithms according to architecture.

In contrast to existing kinematical approaches to finite viscoplasticity of glassy polymers, the formulation proposed is constructed in the logarithmic strain space and related to a six-dimensional plastic metric. Therefore, it a priori avoids difficulties concerning with the uniqueness of a plastic rotation. The constitutive framework consists of three major steps: (i) A geometric pre-processing defines a total and a plastic logarithmic strain measures determined from the current and plastic metrics, respectively. (ii) The constitutive model describes the stresses and the consistent moduli work-conjugate to the logarithmic strain measures in an analogous structure to the geometrically linear theory. (iii) A geometric post-processing maps the stresses and the algorithmic tangent moduli computed in the logarithmic strain space to their nominal, material or spatial counterparts in the finite deformation space. The analogy between the formulation of finite plasticity in the logarithmic strain space and the geometrically linear theory of plasticity makes this framework very attractive, in particular regarding the algorithmic implementation. The flow rule for viscoplastic strains in the logarithmic strain space is adopted from the celebrated double-kink theory. The post-yield kinematic hardening is modeled by different network models. Here, we compare the response of the eight chain model with the newly proposed non-affine micro-sphere model. Apart from the constitutive model, experimental results obtained from both the homogeneous compression and inhomogeneous tension tests on polycarbonate are presented. Besides the load–displacement data acquired from inhomogeneous experiments, quantitative three-dimensional optical measurements of the surface strain fields are carried out.

One of the first models for concrete introduced into such a framework is Mazars’ damage model. A new formulation of this model, called the “μ model” and based on a coupling of elasticity and damage within an isotropic formulation, is proposed herein for the purpose of 3D cyclic and dynamic loadings. Unilateral behavior (i.e., crack opening and closure) is introduced by use of two internal variables. A threshold surface is then associated with each of these variables. The shape of such surfaces has been chosen to model as accurately as possible concrete behavior under various loadings, i.e., tension, compression, shear, biaxial and triaxial, in the aim of simulating a large number of loading types (monotonic, cyclic, seismic, blast, impact, etc.). Applications of this model are presented on plain or reinforced concrete elements subjected to a range of loadings (e.g., multiaxial, cyclic, dynamic). A comparison with experimental results serves to demonstrate the effectiveness of these various selected options.}, 9287 language = {en}, 9288 urldate = {2015-07-21}, 9289 journal = {Materials and Structures}, 9290 author = {Mazars, Jacky and Hamon, François and Grange, Stéphane}, 9291 month = oct, 9292 year = {2014}, 9293 keywords = {Building Materials, Civil Engineering, Concrete, Cyclic loading, Damage models, Finite element calculations, Materials Science, general, Operating Procedures, Materials Treatment, Severe loadings, Structural Mechanics, Theoretical and Applied Mechanics, Thermodynamics of irreversible processes, Unilateral behavior}, 9294 pages = {1--15}, 9295 file = {Full Text PDF:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/NGA887KP/Mazars et al. - 2014 - A new 3D damage model for concrete under monotonic.pdf:application/pdf;Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/DIRBBX26/s11527-014-0439-8.html:text/html} 9296} 9297 9298@techreport{helfer_club_2011, 9299 type = {Compte-rendu de réunion}, 9300 title = {Club utilisateur {Licos}}, 9301 number = {DEC/SEC/LSC/CRR 11-033}, 9302 institution = {DEC/SEC/LSC}, 9303 author = {Helfer, T.}, 9304 year = {2011}, 9305 file = {11-033 CU LICOS 26-05-2011.docx:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/M34RV9QF/11-033 CU LICOS 26-05-2011.docx:application/vnd.openxmlformats-officedocument.wordprocessingml.document} 9306} 9307 9308@article{salvo_experimental_2015-2, 9309 title = {Experimental characterization and modelling of {UO}2 behavior at high temperatures and high strain rates}, 9310 volume = {456}, 9311 issn = {0022-3115}, 9312 url = {http://www.sciencedirect.com/science/article/pii/S002231151400614X}, 9313 doi = {10.1016/j.jnucmat.2014.09.024}, 9314 abstract = {This work presents an experimental characterization of uranium dioxide (UO2) in compression under Reactivity Initiated Accident (RIA) conditions. Pellet samples were tested at four temperatures (1100, 1350, 1550 and 1700 ° C ) and at a strain rate varying over 4 decades ( 10 - 4 – 10 - 3 – 10 - 2 – 10 - 1 /s). The experimental results show that the stress–strain curves cannot be fitted with a unique power law as it is the case at smaller strain rates ( 10 - 9 – 10 - 5 /s). A strain-hardening also appears in most of the tests. The microstructural observations show a pronounced evolution of the porosity at the pellet center during the tests. A hyperbolic sine model which accounts for volume variations (pore compressibility) was therefore proposed to describe the behavior of UO2 on a large range of temperatures ( 1100 - 1700 ° C ) and strain rates ( 10 - 9 – 10 - 1 /s). The Finite Element simulations of the compression tests lead to results (maximum stress, axial and hoop strain distribution, porosity distribution) in good agreement with the measurements. The model was then assessed on a database of more than two hundred creep tests.}, 9315 urldate = {2014-09-30}, 9316 journal = {Journal of Nuclear Materials}, 9317 author = {Salvo, Maxime and Sercombe, Jérôme and Ménard, Jean-Claude and Julien, Jérôme and Helfer, Thomas and Désoyer, Thierry}, 9318 month = jan, 9319 year = {2015}, 9320 pages = {54--67}, 9321 file = {Salvo et al. - 2015 - Experimental characterization and modelling of UO2.pdf:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/S2QIDCDR/Salvo et al. - 2015 - Experimental characterization and modelling of UO2.pdf:application/pdf;ScienceDirect Snapshot:/home/th202608/.zotero/zotero/vzpzva46.default/zotero/storage/7DEXAAIH/S002231151400614X.html:text/html} 9322} 9323 9324@techreport{henrot_equations_2000, 9325 title = {Équations aux dérivées partielles}, 9326 institution = {École des Mines de Nancy}, 9327 author = {Henrot, A.}, 9328 year = {2000}, 9329 note = {Mathématiques tronc commun} 9330}
