Popis: This work presents a comparative study for the progressive damage analysis of double-notched glass/epoxy composites with layups [90/0]s and [45/90/-45/0]s. The material property degradation method (MPDM) is used to model the intra-lamina failure whereas cohesive elements (CE) are employed to account for the delamination at the interfaces. Different fracture mechanics-based and continuum damage mechanics-based failure theories are considered in the MPDM-CE approach and a comparative study of these failure theories is presented. The predictions are compared with the experimental results reported by Hallett and Wisnom [2006]. Reasonably good agreement between experiment results and simulation results is obtained, showing that the MPDM-CE approach can effectively predict the progressive failure in double-notched glass/epoxy composite laminates.
