Abstract
This chapter performs micromechanical damage modeling and explicit finite element analysis on the damage evolution behaviors and failure surface of glass fiber/PC resin thermoplastic composites under quasistatic transverse tension and shear loads using explicit FEA. Microscopic RVE is established using ABAQUS-PYTHON script language. Plane strain state is assumed for long fiber composites. The viscoplastic Gurson model is used to predict the plastic deformation and void growth of the matrix. The fiber/matrix interface failure is simulated by the bilinear cohesive model. The effects of the load mode and the cohesive interface strength on the load responses, the void growth, the strain concentration or localization behaviors, and the failure surface of composites are studied.
