Accurate simulation of delamination with a resin-rich layer-dependent penalty stiffness based on structural cohesive elements

Shell-based cohesive elements tend to overestimate the compression ahead of the crack tip because of approximations in the penalty stiffness. In this study, the higher-order structural cohesive element previously developed by the authors is enhanced with a resin-rich layer-dependent penalty stiffness to improve both co...
