Abstract:A constitutive model is developed for materials involving two or more different phases in their microstructure such as DP (Dual Phase) or TRIP (TRansformation Induced Plasticity) steels. Homogenization of the response of the phases is achieved by the Mean-Field method. One of the phases in TRIP steels is metastable austenite (Retained Austenite) which transforms to martensite upon deformation. A stress-based mechanically induced martensitic transformation model is incorporated in the algorithm in order to capture this behavior.
