摘要: General analysis of the role microstructure in a material fracture behavior is presented. It argued that existence characteristic structural lengthscale implicitly assumed linear mechanics. Fracture microstructural element controls macroscopic apparent properties. In particular, greater size toughness or effective energy. Data for brittle engineering materials, such as ceramics, are analyzed from this viewpoint. Time-dependent and imperfectly elastic also discussed.
