A novel four-linear cohesive law for the delamination simulation in composite DCB laminates
Abstract
Large-scale fiber bridging usually presents in the wake of the crack tip in multidirectional composite DCB laminates, resulting in a significant R-curve phenomenon on the fracture toughness. In order to consider the influence of the fiber bridging on the delamination behavior in FE modelling, a novel four-linear cohesive law is proposed in this study, which is physically established based on the realistic failure mechanism during the...
