Crystallographic texture evolution during forming processes has a significant effect on the anisotropic flow behavior of crystalline material. In this study, a crystal plasticity finite element method (CPFEM), which incorporates the crystal plasticity constitutive law into a three-dimensional finite element method, was used to investigate texture evolution of a face-centered-cubic material -an aluminum alloy. A rate-dependent polycrystalline theory was fully implemented within an in-house

Each integration point in the element was considered to be a polycrystalline aggregate consisting of a large number of grains, and the deformation of each grain in the aggregate was assumed to be the same as the macroscopic deformation of the aggregate. The texture evolution during three different deformation modesuniaxial tension, uniaxial compression, and plane strain compression -was investigated in terms of pole figures and compared to experimental data available in the literature.
