Abstract
This paper presents a finite element (FE) based framework to perform integrated cure and progressive failure analyses of fiber-reinforced polymers. This framework goes beyond the unit cell and is applicable to laminate scales with various layups, geometries and loading cases. Cure induced residual stresses are calculated using a coupled chemo-thermo-mechanical analysis, where the cure-hardening/ instantaneous linear elastic (CHILE) constitutive model is used to capture the hardening evolution of the matrix. After the residual stresses are calculated, a progressive failure analysis step is performed, based on the semi-discrete modeling technique. Through a smart meshing strategy, a failure mode-separation in the formulation, a probabilistic modeling approach and a mesh-objective constitutive model, the enhanced semi-discrete damage model (eSD2M) is capable of predicting complex failure modes as well as failure loads with good accuracy and computational efficiency.
