Comparison of Computational Techniques for Prediction of Delamination Initiation and Propagation in Composite Laminates

In the past few decades, interlaminar and intralaminar damage interaction on composite laminates has been extensively investigated in order to predict failure. It is widely known that predictive modelling of composite structures failure -specifically during the manufacturing stagecould significantly reduce the production cost and time. In many cases, delamination is the main threat leading to failure. Despite having an enormous amount of research via both numerical and experimental, comparison between different techniques for predictive modelling of delamination initiation and propagation results in significant discrepancies [1].
