Integrated Computational Engineering (ICE) is a valuable and cost effective resource for ensuring structural integrity and damage tolerance of future aerospace vehicles that are made with laminated fiber reinforced composite laminates. Towards that end, the variational multiscale cohesive method (VMCM) reported by the authors in previous AIAA SDM conferences, 23–26 is extended further to address problems of mixed mode in-plane crack propagation in fiber reinforced laminates. A set of experimental results obtained using a single edge notch eccentric three point bend test is used for validating the VMCM predictions. Further the applicability of VMCM is demonstrated through simulation of mixed mode in-plane crack propagation for different specimen geometries and different loading conditions.
