To efficiently perform by matching simulation operation of macro structure and micro structure when simulating the behavior of heterogeneous material having micro structure where a plurality of material phases having different material characteristic such as a rubber elastic body are dispersedly disposed.
Superelastic potential and material constant are defined by performing the simulation operation by deforming a micro scale model reproducing the micro structure of the heterogeneous material, and macro scale simulation operation is performed by using the macro scale model reproducing the structure body including the heterogeneous material based on the superelastic potential and the material constant. The result of the strain at the representative point of disposition part of the heterogeneous material is obtained among the macro scale simulation operation result, and the micro scale simulation 2 is performed by defining the displacement of boundary area in the micro scale model from the strain and by making this displacement as the boundary condition of the micro scale model.
