Understanding and Predicting Interlaminar Stresses

This course covers the comprehensive understanding of interlaminar stresses in laminates and their prediction. It starts with the mechanics of laminates and the classical lamination theory, explaining how to obtain the ABD Matrix for a laminate. The course further discusses the importance of symmetric, anti-symmetric, and quasi-isotropic laminates. It also provides insights into the determination of stresses and strains in each ply of a laminate and the application of appropriate failure theories. The course then delves into the prediction of delamination, explaining the mechanics of interlaminar stresses at the free edges of a laminate, and how they are induced. It concludes with the assessment of delamination using stress-based and fracture mechanics-based approaches.
