| Abstract Scope |
Grain boundary hardening effect is an important but difficult topic in crystal plasticity finite element method (CPFEM). CPFEM Models accounting for grain boundary effect are critically reviewed from 3 aspects: 1) The key gradients in the model, 2) Comparison to the simple two-phase composite model, 3) Comparison to the "real or ideal" slip profile evolution. Based on these critical reviews, the Wagoner super-dislocations (SD) model for grain boundar hardening is developed with an emphasis on its simplification. Performance of the simplified model is evaluated. |
