摘要
The damage and fracture criteria proposed to describe the damage accumulation processes in metallic specimens, rocks, and Earth's crust during earthquake preparation are considered. The efficiency of application of these criteria for an analysis of damage on various scale levels is shown. The transition of fracture from one hierarchical level to another higher level is discussed.
