Determining the Parameters of Microcracks from Their Electromagnetic Radiation Signals

Resumo

This paper proposes a model for determining the characteristics of the evolution of the microcrack field in a loaded rock sample from electromagnetic radiation signals. Calculations were made, whose results were summarized in the form of spatial-temporal tables. Factors determining changes in the hierarchy of microcracks were established. The adequacy of the model was verified using the Zhurkov concentration criterion. Regions of scale invariance were revealed in graphs of the concentration of microcracks versus their size in logarithmic coordinates.
