摘要
A material shape simulation apparatus for accurately simulating deformation of a three-dimensional woven fiber material is provided. A material shape simulation apparatus 100 includes: an orientation vector field generation unit 210 that generates a model shape orientation vector field on three-dimensional meshes of a model shape of a three-dimensional woven fiber material which is obtained by stacking a plurality of sheets of two-dimensional woven fabric made of X-yarn extending in an X-direction and Y-yarn extending in a Y-direction and binding them with Z-yarn extending in a Z-direction; a parameterization unit 220 that searches for a gradient vector for calculating a material shape orientation vector field, which is an orientation vector field of a material shape before deformation of the model shape, from the model shape orientation vector field; and an orientation vector updating unit 230 that updates the model shape orientation vector field by applying a condition of preserving a volume between the model shape orientation vector field and the material shape orientation vector field and a condition that neither the X-yarn nor the Y-yarn expands or contracts.
