Model of Self‐Organization of an Ensemble of Cracks Radiating Sound

Journal of Applied Mechanics and Technical Physics Aims and scope

Abstract

A model of self‐organization of cracks arising in a rock specimen (granite) compressed by a press is proposed. The model is based on the assumption of acoustic wave interaction between the cracks. To construct the model of self‐organization of cracks, solutions of the Fokker–Planck equation are used. The experimentally observed spontaneous increase in the activity of acoustic emission, spatial and temporal clusterization, and formation of a fractal structure in rock specimens under constant and slowly varying loads are explained.
