Acoustic Emission Monitoring and Failure Precursors of Sandstone Samples under Various Loading and Unloading Paths
To explore the failure precursors of hard rock, a series of triaxial loading and unloading experiments were carried out on sandstone sample using the acoustic emission systems. The extreme-point symmetric mode decomposition method (ESMD method) was used to denoise and reconstruct the AE data. The AE...
