Multi-scale crystal plasticity finite element method (CPFEM) simulations for shear band development in aluminum alloys

Multi-scale Crystal Plasticity Finite Element Method (CPFEM) simulations including macro-, meso- and microscale are applied to study the shear band development in cold-rolled AA5182-H28 aluminum alloy sheets under simple shear along various directions with respect to the rolling direction. The resolution and the computational cost in predicting the development of shear bands are compared among the three simulation scales. In macro-, meso- or …
