The purpose of this study is establishment of design methods for competitive swimwear using numerical analysis. The anisotoropic hyperelastic model is introduced into swimwear materials and the applicability of the model to swimwear is estimated. The swimwear is made of the fabric material. The materials have two mechanical properties. The one is nonlinear elasticity which is regarded as hyperelasticity like rubber. Another is anisotropic that depend on the directions of two fiber families. The properties of swimwear fabrics were estimated by uniaxial tensile tests, and anisotropic hyperelastic model is applied to the numerical modeling. The materials are plain weave and show anisotropic properties. So, Asai model which is possible to adjust stretch rigidity and shear rigidity separately is applied to them. Then, we determine the material parameters of them and verified their accuracy.
