PROBLEM TO BE SOLVED: To provide a dynamic characteristic simulation method and device for a composite material in a structure wherein the composite materials are combined, simulating dynamic behavior of the composite material used for a tire or the like.;SOLUTION: This dynamic characteristic simulation method and device has a plurality of three-dimensional finite elements each having the same size, adjacently disposed in three directions orthogonal to each other. By distributing the three-dimensional finite element of a shape model reproducing a cubic shape of the composite material to at least a matrix phase portion and a dispersion phase portion in finite element units, a composite material model reproducing a microscopic structure of the composite material is generated, and finite element analysis of dynamic characteristics are performed by use of the generated composite material model.;COPYRIGHT: (C)2005,JPO&NCIPI
