Development a refined numerical model for evaluating the matrix cracking and induced delamination formation in cross-ply composite laminates

In this study, at first the dominant micro scale failure modes including fiber–matrix debonding and matrix cracking are studied in 2D RVEs extracted from the layer 90° in different cross-ply laminates. To model the debonding and matrix cracking formation in RVEs, cohesive zone model (CZM) and Extended finite element method (XFEM) are applied. Then to investigate induced delamination formation originates from the tips of matrix cracking as a...
