Effect of interfacial energy combined with geometrical nonlinearity on the finite fracture analysis of composite single-lap joints

This paper investigates the effects of interface energy and geometrical nonlinearity on the fracture behavior of composite single-lap joints. The physical and mathematical model is based on the finite fracture mechanics and the interface elasticity. An experiment-based approach is utilized to determine the unknown interfacial parameters. A stress-energy coupled criterion is employed to predict the failure load based on the framework of finite...
