Abstract:
It is established that the development of a localized plastic strain during compression of samples of rocks (sylvinite, marble, and sandstone) deformed by different micromechanisms has an autowave character. It is shown that the velocity of propagation of autowaves arising in the samples under compression is 10−5 to 10−4 m/s (0.3 to 3.0 km/g) and is close to the velocity of slow waves observed in the Earth’s crust after earthquakes or rockbursts.
