dc.description.abstract | Fracture and failure mechanics of advanced materials and structures with interfaces was investigated both experimentally and numerically. Dynamic fracture mechanics was used to model the phenomena when a main crack was encountering an interface. Critical dynamic fracture mechanics parameters of an infinitesimal kinked crack were determined through a relation of crack speeds, kinked angles and the other parameters of the main incident crack. Strength-based criteria were proposed to predict the interfacial debonding ahead of a main crack. In these studies, interface strengths were found to be crucial parameters for predicting crack propagation along the interface. Hence, a new specimen design to measure intrinsic interface strengths of dissimilar materials was performed, and accurate interfacial strengths were obtained. | |
