Abstract
The crystal plasticity finite element method (CPFEM) has emerged as an important method for studying materials on a mesoscopic scale. However, a significant obstacle to the application of CPFEM is the numerous material parameters associated with it. This study selected a physics-based CPFEM incorporating the non-crystalline shear band formation mechanism as it can stimulate both work-hardening and strain-softening mechanisms. A three-dimensional smooth specimen model was established to simulate the tensile test. The effects of six fitting crystal plasticity material parameters on the yielding stress, work-hardening behavior, and strain localization behavior are. In addition, the influencing mechanisms are discussed.
