Public ISBD [article]  inActa materialia > Vol. 58 N° 4 (Fevrier 2010) . - pp. 1152–1211 Titre : Overview of constitutive laws, kinematics, homogenization and multiscale methods in crystal plasticity finite-element modeling : Theory, experiments, applications Type de document : texte imprimé Auteurs : F. Roters, Auteur ; P. Eisenlohr, Auteur ; L. Hantcherli, Auteur Année de publication : 2011 Article en page(s) : pp. 1152–1211 Note générale : Métallurgie Langues : Anglais (eng) Mots-clés : Crystal plasticity Twinning Indentation Multiphase steel Anisotropy Résumé : This article reviews continuum-based variational formulations for describing the elastic–plastic deformation of anisotropic heterogeneous crystalline matter. These approaches, commonly referred to as crystal plasticity finite-element models, are important both for basic microstructure-based mechanical predictions as well as for engineering design and performance simulations involving anisotropic media. Besides the discussion of the constitutive laws, kinematics, homogenization schemes and multiscale approaches behind these methods, we also present some examples, including, in particular, comparisons of the predictions with experiments. The applications stem from such diverse fields as orientation stability, microbeam bending, single-crystal and bicrystal deformation, nanoindentation, recrystallization, multiphase steel (TRIP) deformation, and damage prediction for the microscopic and mesoscopic scales and multiscale predictions of rolling textures, cup drawing, Lankfort (r) values and stamping simulations for the macroscopic scale.
