Modélisation multidomaine du comportement magnéto-mécanique des aciers dual-phases

Abstract : The microstructure and mechanical behavior of dual-phase steels are highly sensitive to the variation of the process (heat treatments). Online control by magnetic method is relevant. A measurement under applied stress must be considered. The dual-phase is a two-phase medium (ferrite / martensite). Each phase can be considered as a sphere embedded in a homogeneous equivalent medium. The model used for each phase is based on a magneto-mechanical coupled model. This is an explicit single crystalline model representative of the behavior of the corresponding phase. Localization rules allow the simulation of the two-phases medium. Experiments and modeling are compared.
