To analyze the strain in a material exhibiting strong compressibility with high accuracy by performing analysis in which damping properties of a compressible material is accurately expressed.SOLUTION: Provided is a deformation analysis method for a compressible material having nonlinear viscoelastic behavior. A superposition model M0 is used, equipped in parallel with a linear viscoelastic portion by a generalized Maxwell model M1 and a compressible viscoelastic portion (modified Gurson model M2) having a yield condition dependent on hydrostatic stress, and the nonlinear viscoelastic behavior in the compressible material is made to be simulated.SELECTED DRAWING: Figure 2
