Аннотация
© 2020 Elsevier B.V.The present study is devoted to evolution of rocks in the fracture process. Initially the rock is considered as an ideal medium with no cracks. Rock formation is assumed in the form of a nested self-similar hierarchical structure. The hierarchical structure scheme is chosen in accordance with the experimentally verified criterion of fracture. The failure probability of the lowest structure level represents a function of time, temperature, material parameters and loading conditions. Knowing the failure probabilities of each structure level allows one to calculate the stress dynamics in a rock material, failure volumes for each hierarchy level, energy release, etc. The influence of temperature, type of the hierarchical structure, rock material, stress rate on the fracture dynamics is considered. The results of calculations of the rock fracture dynamics are compared with the results of experiments. This study can be seen as an attempt to explain the stability of the Gutenberg-Richter law.
