When performing large deformation simulations, it is typically assumed that the workpiece is isotropic. This means that the thermomechanical properties of the material do not have any directional dependence. However, this assumption may not always be appropriate since many polycrystalline materials develop anisotropic (directionally-dependent) properties with increasing deformation. Anisotropy can be caused by changes in the microstructure due to deformation. This article describes how DEFORM offers several options to modal anisotropic behaviour and texture evolution.
