摘要：
A crystal plasticity finite element method (CPFEM), considering both crystallographic slip and deformation twinning, was used to simulate texture evolution and macroscopic properties of AZ31 Mg alloys. To capture grain reorientation due to deformation twinning in twin-dominated deformation, a predominant twin reorientation (PTR) model was considered. The validity of the proposed theoretical framework was demonstrated through comparison of simulated results, such as texture evolution and macroscopic properties, with the experimental results and measurements. The simulation of texture evolution and macroscopic properties of AZ31 Mg alloys was shown to be in good agreement with the corresponding experimental results. (C) 2009 Elsevier B.V.
