Abstract
The deformation behavior of metals and rocks is analyzed. The stages of damage accumulation, the formation of deformation localization zones, the length distributions of the number of microcracks in metallic samples and faults in Earth’s crust, and the time dependences of acoustic emission and seismic events before the fracture of specimens and earthquakes are considered. The main laws of the damage accumulation kinetics before the fracture of specimens and the seismicity dynamics before an earthquake are found to be similar.
