Energy Evolution and Acoustic Emission Characteristics of Sandstone Specimens under Unloading Confining Pressure
The acoustic emission characteristics of rock specimens under different initial unloading confining pressures were tested to obtain the damage and rupture characteristics of the sandstone unloading confining pressure path. The CT scan and three-dimensional reconstruction of the fractured rock specim...
