Transformation-induced-plasticity (TRIP) steels exhibit complex material behavior, because of martensitic transformation during plastic deformation. This study aims to modeling the mechanical behavior for such TRIP materials using a two kinematic and isotropic hardening model taking into account the evolution of the martensitic transformation rate during mechanical loading. This model was developed on austenitic stainless steels material and could be extended to describe different TRIP materials behavior. This model was then implemented in FE software abaqus/explicit in order to describe mechanical properties and martensitic transformation evolution during isothermal mechanical process. Simulation of forming process with FE abaqus/explicit was carried out and compared to experimental data. It was concluded that the numerical results show a good agreement with experimental ones in terms of mechanical properties and martensitic transformation rate.
