Study on the Frequency Distribution of AE Amplitude and the Fractal of the Crack in the Fracture Process of the Rock

It is well known that the frequency distribution of the earthquake scale shows straight relation on the log-log graph. This relation is considered as the Fractal of the earthquake scale at present. The Fractal is seen in the general fracture phenomenon including an earthquake. But, the relation between the Fractal and the mechanism of the fracture is not made clear.In this study, the AE in the fracture process of the various rocks was measured and the frequency distribution ofAE amplitude was examined about the Fractal. As the result, the characteristics of the AE amplitude distribution changed by the scale, but the Fractal dimension of the crack distribution proved that it didn\u27t change by the scale
