Accurate simulation of delamination with a resin-rich layer-dependent penalty stiffness based on structural cohesive elements
Xiaopeng Ai, Christos Kassapoglou, Boyang Chen
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 struct…

A new approach for the determination of through-thickness and free-edge stresses in composite laminates based on structural elements
Xiaopeng Ai, Christos Kassapoglou, Boyang Chen
Thin shell elements based on the Kirchhoff-Love hypothesis account for only three stress components: the in-plane normal stresses and the in-plane shear stress. The out-of-plane st…

Structural cohesive element for the modelling of delamination in composite laminates without the cohesive zone limit
Xiaopeng Ai, Boyang Chen, Christos Kassapoglou
Delamination is a critical mode of failure that occurs between plies in a composite laminate. The cohesive element, developed based on the cohesive zone model, is widely used for m…
