Anisotropic hyperelastic model considering fiber dispersion for artificial leather

Abstract

In this paper, an anisotropic hyperelastic model for artificial leather considering fiber dispersion was investigated. Fiber-reinforced elastomer such as artificial leather, show non-linear elastic characteristics, and it depends on the principle direction and dispersion of the reinforcing fibers. In this research, the fiber-reinforced structural model⁽¹⁾ was modified for the artificial leather for sports equipment. Uniaxial loading tests were conducted to observe the effect of the direction of tensile loading tests on the stress-strain relationships. The validity of the proposed model was evaluated in comparison with the experimental results. The results of the numerical analysis and the uniaxial tensile tests showed good applicability of the anisotropic hyperelastic model considering fiber dispersion in the artificial leather.
