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
The paper introduces a method that uses structural cohesive elements with a penalty stiffness derived from resin‑rich layers to recover out‑of‑plane stresses in thin‑shell models o…

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…
