Application of finite fracture mechanics for predicting free edge delamination in multi-layered materials under various loading conditions Mohammad Burhan (23656408) PUREID: 613047512 Finite fracture mechanics free edge delamination semi-elliptical crack This thesis investigates the free edge effect in multi-layered composites, where stress concentrations at dissimilar interfaces induce delamination. A novel 3D Finite Fracture Mechanics (FFM) criterion is introduced to predict delamination under quasi-static, thermal, and fatigue loading conditions. Semi-analytical frameworks are developed to calculate interlaminar stresses and energy release rates (ERR) along semi-elliptical cracks using advanced parametric Finite Element models. These frameworks are extended to hybrid metal/composite laminates, improving fracture predictions. The criterion is validated against experimental tests, offering accurate predictions of failure loads and crack extension in symmetric laminates subjected to various loading scenarios.<i><br></i> 2026-10-01T16:34:01Z Text Thesis 10.17034/32640123.v1 https://figshare.com/articles/thesis/Application_of_finite_fracture_mechanics_for_predicting_free_edge_delamination_in_multi-layered_materials_under_various_loading_conditions/32640123 All Rights Reserved
