抄録

The purpose of this study is to present the applicability of homogenization methods based on heterogeneous microstructure in multi-constituent steels. At first, basic equations of a standard elastoplastic constitutive model and the homogenization methods have been discussed to describe nonlinear stress-strain curves of metallic materials. Here the homogenization methods have been classified into three types with the theoretical differences in concept. Numerical demonstrations for Dual-Phase steel have been performed to express the potential of these homogenization methods. The results of numerical demonstrations have indicated that a class of the numerical homogenization approaches is especially useful in both a quantitative evaluation of macroscopic material response and an investigation of microscopic mechanism in consideration of morphology of microstructure.
