断裂力学问世以来,引起了国内外工程界的高度重视,而且在发展新材料、新工艺和航空、船舶、发电设备、化工容器以及机械制造等部门得到了应用,特别是线弹性断裂力学开始广泛地应用于工程实践.开始从“无损伤设计”向“容限损伤设计”(或称“控制断裂设计”)转变.传统的强度理论,不能解决裂纹 Since the advent of fracture mechanics, it has aroused great attention of engineering community at home and abroad, and has been applied in the development of new materials, new technology and aviation, shipbuilding, power generation equipment, chemical containers and machinery manufacturing departments, especially linear elastic fracture mechanics It has been applied in engineering practice to begin the transformation from “non-destructive design” to “allowable damage design” (or “controlled fracture design”). The traditional theory of strength can not solve the problem of cracks
