Modeling damage initiation and growth in discontinuous random fiber composites Conference Paper uri icon

abstract

  • The effects of fiber and resin properties on the structural performance in discontinuous fiber reinforced composites was studied by representative volume element method (RVE). RVE explored the damage initiation and growth in discontinuous structural reaction injection molded composite. RVE used a moderate strain elasto-plastic-fracture constitutive formulation for the resin based on multiplicative decomposition of the deformation gradient into elastic and plastic components. The constitutive formulations for the resin and fiber were implemented into a commercial finite element program, ABAQUS, as a user material subroutine to track damage initiation and growth.
