摘要: The method to represent a general infinitesimal deformation as moment tensor is proposed and the physical meaning of in case microcracking made clear. Developing measuring analysis system for acoustic emission waveform analysis, these components due can be determined experimentally. remarkable this study established evaluate with dynamic Green's function finite media by computer simulation difference iterative deconvolution multiple function.
