【Abstract】 Based on interfacial fracture mechanics, the variational rule of the interfacial fracture toughness with respect to the mixture mode was presented in this paper . Using the interfacial fracture energy and mixture mode as the primary microstructural parameters, data reduction methods in testing the mode I fracture toughness of the material interface were studied. This provided necessary experimental means to evaluate the fracture resistance of actual material interfaces.更多还原
