Crystal Plasticity Finite Element Simulation of Aluminium Deformation

Abstract

Crystal plasticity deformation of aluminium plays an important role on the investigation of macro deformation. In this paper, to discuss the effect ot crystal plasticity on the aluminium material behavior, crystal plasticity theory and macro finite element was combined together. The basic theory of crystal plasticity and finite element was introduce and the simulation result of aluminium was given. The stress and strain distribution was discussed and the efficient of the method was shown. It is shown that the orientation of the material and other micro character of the materials all influence the plasticity behavior of the material greatly.
