A new crystal plasticity model for face-centered cubic metals exhibiting deformation twinning is presented and assessed based on a comprehensive and original experimental dataset for twinning-induced plasticity (TWIP) steel. Various scale transition schemes are tested, including a finite-element representation of the polycrystalline aggregate and a simplified Taylor-type modeling of pairwise interactions...
The plastic anisotropy of textured polycrystalline aggregates is investigated using three micro-macro averaging schemes: a crystal plasticity based finite element model (CPFEM), the viscoplastic self-consistent (VPSC) scheme of Lebensohn and Tomé [R.A. Lebensohn C.N. Tomé, Acta Metall. Mater. 41 (1993) 2611–2624], and a “multisite” model that is based on a simplified treatment of the interaction of...
