Damage evolution on different scale levels

The patterns of multiple fractures in a localized zone at the notch tip of metallic specimens are studied at different stages of static and cyclic loading. Cumulative number-length distributions of microcracks in the localized zone of fracture and amplitude distribution of acoustic emission signals accompanying the development of fracture are calculated. The influence of metal structure and loading conditions on multiple fracture kinetics is considered.
