In practical projects, structural fracture often undergoes complex stresses. The studies on the fracture mechanism of mixed mode cracks are of important theoretical significance and practical implication. Based on the mi...

In order to obtain the criteria and precursor characteristics of critical rock fracture, laboratory experiments on the characteristics of acoustic emission (AE) of gritstone specimens under uniaxial compression are carri...

The mathematical methods of FFT and wavelet transform are used to deal with the acoustic emission (AE) frequency information of rock fracture firstly. Combined with the spectral distribution of AE signal, the main respon...
