摘要: In this paper, we first introduce various polycrystal plasticity models including the Visco-Plastic Self-Consistent (VPSC) model, Elastic-Plastic (EPSC) and Elastic (EVPSC) as well twinning Predominant Twin Reorientation (PTR) model Twinning De-Twinning (TDT) with emphasizing on characteristic differences between these models. Then, demonstrate that EVPSC-TDT is able to capture key features of large strain behaviour HCP materials under deformation processes uniaxial tension compression, simple shear, torsion.
