Kinetic similarity of fracture processes on various scale levels
Source abstract
Abstract
Common kinetic features of multiple fracture of metallic specimens tested at different loading conditions were studied and used for an analysis of seismic activity accompanying multiple formation of faults in the earth crust. The study revealed the similarity of basic regularities in the dynamics of seismicity before earthquake and in kinetics of damage accumulation before specimen fracture, estimated by acoustic emission and metallographic methods. The results obtained confirm the ideas of self-similarity and the hierarchical sequence of multiple fractures, and they provide a physical basis for prediction of the critical events at various scale levels.
