摘要
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 ,揭示了材料界面增韧的主要力学机理 :一是提高界面断裂韧性 ,二是实现最佳断裂路径 ,并以此为依据 ,分析了材料界面强韧化设计的主要原理和方法 。
Based on the interfacial fracture mechanics, this paper presents the principal toughening mechanics mechanism for the material interfaces using interfacial fracture energy and mixture mode as primary microstructural parameters: one is to improve interfacial fracture toughness, the other is to realize optimum fracture path And according to the toughening mechanism the main principles and methods in toughening design of material interfaces are studied, which provides theory basis for the actual interface design
