Abstract

Dual phase (DP) steels are high strength steels used mainly in the production of vehicle bodies, currently about 74% of the structural components are made of this type of material. These DP steels are composed of a soft ferrite matrix with a hard, martensite phase. In this research, mechanical properties characteristic of these materials is linked, establishing dependence between volume fractions of each phase and simulations of the mechanical behavior in different situations are developed. Implementing a 2D bilinear plasticity model from the synergy of three design programs, regions of the martensitic phase of the material were generated in a 3D space. In the same way, these inclusions were parameterized and modeled together with a ferritic matrix. Then, using FEM to simulate 3D micromodeling (RVE), stress-strain diagrams are obtained.  Finally, the results show deviations of 10% on average from the experimental values.
