CONSTITUTIVE MATERIAL MODEL OF FIBER- REINFORCED COMPOSITES AT FINITE STRAINS IN

This paper presents the Comsol Multiphysics implementation of anisotropic hyperelastic material models for the two-dimensional stress and deformation response of fiber-reinforced composites that experience finite strains. The composites are composed of rubber matrix which is reinforced by one or two families of fibers so that the mechanical properties of the composites depend on the fiber directions. In order to clearly show the good performance of the constitutive model, we present 2D numerical simulations of a stretched laminated rectangular plate with a hole
