Abstract

The motivation for the present work is to enable the designer to achieve optimum structural performance in discontinuous fiber reinforced composites by investigating the influence of fiber and resin properties. This is accomplished by exploring the damage initiation and growth in discontinuous structural reaction injection molded (SRIM) composite using a representative volume element (RVE). The RYE utilizes a moderate strain elasto-plastic-fracture constitutive formulation for the resin based on a multiplicative decomposition of the deformation gradient into elastic and plastic components. An elastic-fracture large strain constitutive response is utilized for the fiber. The resin properties (coefficient of linear ther
