Experimental and numerical investigation of the mixed mode delamination of monolithic laminates exhibiting severe fiber bridging

A recently developed cohesive zone traction-separation formulation for mode I facesheet to core disbonding, which includes the effects of fiber bridging in a novel way, is extended to account for mode II and mixed mode delamination. The pure mode I and mode II behavior of the model is calibrated based on traction separation curves which are extracted from Double Cantilever Beam (DCB) and End Notched Flexure (ENF) experiments utilizing the J...
