A Crystal Plasticity Formulation for Simulating the Formability of a Transformation Induced Plasticity Steel

The enhancement in formability of new advanced high strength steels (AHSS), such as duplex stainless steel, arises from increased hardening and ductility from complex deformation mechanisms, such as the transformation-induced plasticity (TRIP) effect. However, the interaction of dislocation and transformation mechanisms during deformation for various strain paths presents a challenge in evaluating formability. High fidelity simulation tools for …
