To highly accurately represent behaviors of a polymer material when largely deformed. [ Solution ] A simulation method for a polymer material according to the present invention includes an imaging step S1 for acquiring electron beam transmission images of the polymer material 2, a step S 2 for constructing a three-dimensional image 21 of the polymer material, a model defining step S3 for defining a polymer material model 26, and a step S4 for carrying out a deformation simulation based on the polymer material model 26. The model defining step S3 includes a step S31 for constructing, based on the three-dimensional images 21 of the polymer material, a three-dimensional structure of the polymer material in which a filler portion 27 and a polymer material portion 28 are discriminated, a step S33 for disposing a filler model 35 in the filler portion 27, a step S34 for disposing a coarse-grained model 36 in the polymer material portion 28, and a step S37 for calculating structural relaxation based on a molecular dynamics calculation by the use of the filler model 35 and the coarse-grained model 36. |
