| Title | "ISOTROPIC AND ANISOTROPIC PLASTICITY" ＜Abstract＞ In this presentation, the description of constitutive relationships for the plasticity of metals is reviewed. This is mostly about the yield condition which, with a few assumptions, is sufficient to completely define the plastic behavior of a continuum point. After a brief introduction, the discussion splits into two main sections: 1) isotropic and anisotropic plasticity under isotropic hardening and; 2) Anisotropic hardening. In the latter, the emphasis is put on distortional plasticity. Finally, a brief introduction of the finite element (FE) implementation with a recently developed non-iterative stress integration approach is explained [1]. The results of the forming simulation of a B-pillar made of a TRIP 1180 steel sheet is shown for application purpose and to prove the robustness of a distortional plasticity model and its FE implementation.
