The fracture mechanics of delamination tests
WebDelamination and interfacial fracture are dominant failure mechanisms of laminated composites and multilayered systems. They may occur as localized or diffuse events and … WebDelamination is a critical failure mode in composites, not because it causes the structure to break, but because it splits the composite in different layers not connected between them, modifying the structural performance of the composite and leading to its failure because of other mechanical phenomenons such as buckling, excessive vibration, or …
