Document Type and Number:
WIPO Patent Application WO/2015/072206
Kind Code:
A1
Abstract:
[Problem] To highly accurately represent the behavior of a polymer material during significant deformation thereof. [Solution] A polymer material simulation method according to the present invention includes an imaging step (S1) for acquiring electron beam transmission images of a polymer material (2), a step (S2) for constructing a three-dimensional image (21) of the polymer material, a model configuration step (S3) for configuring a polymer material model (26), and a step (S4) for carrying out a deformation simulation on the basis of the polymer material model (26). The model configuration step (S3) includes a step (S31) for constructing, on the basis of the three-dimensional image (21) of the polymer material, a three-dimensional structure of the polymer material in which a filler portion (27) and polymer material portion (28) are distinguished, a step (S33) for disposing a filler model (35) in the filler portion (27), a step (S34) for disposing a coarse graining model (36) in the polymer material portion (28), and a step (S37) for using the filler model (35) and coarse graining model (36) to calculate structural relaxation on the basis of molecular dynamics calculation.
