Relationship between frequency of electromagnetic radiation induced by rock fracture and the elastic parameters
岩石破裂电磁辐射频率与弹性参数的关系

In order to know much more about the characteristics of electromagnetic radiation induced by rock fracture, this study assumes that the electromagnetic radiation is created by the atomic perturbation during rock fracture, and uses the Crack Opening Displacement method to calculate the crack width. We find out the relationship between the frequency and the elastic parameters. By the model of infinite fiat with impenetration crack model, we calculate the frequency range of the electromagnetic radiation during several rock fracture which is from middle to high frequency. The results indicate that the frequency changes with the elastic parameters.
