Abstract

In this study, in order to analyze deformation mechanism in rolling process and predict its yield surface finite element polycrystal model (FEPM) has been developed. Also numerical simulations for deep drawing process of AZ31 magnesium sheet were conducted at elevated temperature. Numerical simulation results for rolling process were compared with experiments of pole figure. For yield surface, the results indicated shift of yield surface along the biaxial strain direction denoting Bauschinger effect and strong anisotropic which is advantageous to deep drawing. Simulation results for limiting drawing ration (LDR) in cup drawing simulation agreed well with experimental observations.
