摘　　要：本文基于界面断裂力学理论 ,以界面的断裂能和混合度为基本细观参数 ,揭示了界面断裂韧性随断裂混合度的变化规律 ,综述了双材料界面纯Ⅰ型断裂韧性的测定方法 。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.
