High-performance full-field crystal plasticity with dislocation-based hardening and slip system back-stress laws: Application to modeling deformation of dual-phase steels

This paper presents a microstructural cell-level crystal plasticity model aimed at predicting elasto-plastic, anisotropic, rate- and temperature-sensitive deformation of polycrystalline aggregates subjected to large plastic strains. The crystallography-based model embeds strain-path aware dislocation-based hardening and slip-system-level kinematic back-stress laws. The crystal-level response is linked to the microstructural cell-level response...
