Prediction of Cohesive Zone Length and Accurate Numerical Simulation of Delamination under Mixed-mode Loading

This article presents an approach to accurately predict the Length of Cohesive Zone (LCZ) and model delamination under mixed-mode loading. A novel expression for estimating the cohesive zone length for the structure subjected to mixed mode delamination is proposed. The proposed expression of LCZ is validated for various structural configurations like mixed-mode delamination specimen, ply-drop, and L-bend. Besides, the effect of maximum...
