Web2 days ago · Crystalline material is commonly used in human society, crystal plasticity finite element (CPFE) method is an effec- tive way to explore the grain scale thermodynamics behaviors of crystalline ... Crystal plasticity is a mesoscale computational technique that takes into account crystallographic anisotropy in modelling the mechanical behaviour of polycrystalline materials. The technique has typically been used to study deformation through the process of slip, however, there are some flavors of crystal plasticity that can incorporate other deformation mechanisms like twinning and phase transformations. Crystal plasticity is used to obtain the relationship between stress and st…
