PROBLEM TO BE SOLVED: To provide a method and device for obtaining a calculation result equivalently to the conventional manner in creating the model of composite materials where particles are dispersed in matrix materials, and for efficiently creating a model in a short time.;SOLUTION: A first mesh model in which the region of a whole compound rubber is mesh-divided and a second mesh model in which the region of dispersed filler particles are mesh-divided are created, and the second mesh model is arranged in the first mesh model. In a region where the elements of the second mesh model and the elements of the first mesh model are overlapped, the displacement of the nodes of the overlapped elements of the second model is constrained by the displacement of the node of the overlapped elements of the first mesh model. Furthermore, material constants are applied so that the sum of the values of material constants to be applied to the overlapped elements of the first mesh model and the values of material constants to be applied to the overlapped elements of the second mesh model can approximate to the values of the material constants owned by the filler particles.;COPYRIGHT: (C)2009,JPO&INPIT
