Elasto-plastic large deformation analysis of bi-material components by FEM

Abstract

This paper presents the modeling of large elasto-plastic deformations in bi-material engineering components by employing the conventional finite element method (FEM). The updated Lagrangian Approach has been used to take into account the large deformations occurring in the domain. The Von-Mises yield criterion with isotropic hardening has been used to model the elasto-plastic behaviour of the material. Bilinear and multilinear plasticity models have been used to model the plastic behaviour of the material. Finally, several numerical problems are solved using FEM to demonstrate the applicability of this method in the modeling and simulation of large deformation phenomenon in bi-material components.
