Research on acoustic emission precursor characteristics of coal sample unloading failure based on discrete wavelet analysis
Abstract Acoustic emission information can describe the damage degree of rock samples in the process of failure. However, as a discrete non-stationary signal, acoustic emission information is difficult to be effectively processed by conventional methods, while wavelet analysis is an effective method...
