Abstract
In this paper, we estimated the applicability of an anisotropic hyperelastic model to the fabric of a competition swimwear. The fabric of a competition swimwear consists of chemical fiber. The fabric shows anisotropy that depends on fiber orientation angle. We used the model as the anisotropic hyperelastic model which was able to adjust each axial stiffness and share stiffness. The material parameters of the anisotropic hyperelastic model for the finite element method (FEM) analysis were determined by uniaxial tension test of the fabric. In order to show the applicability of the anisotropic model, we carried out FEM analysis. As a result, we clarified the mechanical characteristic of the fabric of the competition swimwear. The material consisting of a textile has orthotropy. In addition, we showed that the mechanical characteristic of the fabric of the competition swimwear could be reproduced by the anisotropic hyperelastic model.
