Realizing quasi-VPSC and quasi-Taylor Model by Varying the Boundary Conditions in Submodel of Crystal Plasticity FEM

The uniform-field Taylor model, mean-field visco-plastic self-consistent (VPSC), and full-field crystal plasticity finite element method (CPFEM) are three typical and inherently different crystal plasticity (CP) models. In this report, these three CP models were realized within the CPFEM framework via Submodel modeling techniques. In the full-constraint Taylor model, the strain history from the Wholemodel was applied to all finite element method (FEM) nodes, while the strain from the Wholemodel was placed only on the boundaries of the Submodel in the VPSC model. The predicted textures with the Taylor, VPSC, and CPFEM models were compared, and the rolling textures at macroscopic scale were acceptably captured, and the micro-bands were also predicted by the CPFEM and VPSC. Finally, the contribution and limitations of this integrated modeling method were discussed.
