Rocks are riddled with a large number of pre-existing microcracks (Ashby 1986; Yu and
Feng 1995), which have significant influences on the strength, deformation, and rupture …

The objectives of this study are as follows: To establish the relationship between the
acoustic-emission (AE) parameters and mechanical-failure mechanism of tantalum-niobium …

High-frequency components in acoustic emission (AE) or seismic radiation attract much
attention as they are directly related to the fracture process. One of the main issues in our …

Acoustic emission (AE) signals contain substantial information about the internal fracture
characteristics of rocks and are useful for revealing the laws governing the release of energy …

It is of great practical significance to study the microscopic mechanisms and strength
damage laws of deep rock masses under the coupling action of water and rock. The pore …

In this paper, we report a detailed overview of non-destructive techniques, specifically
Acoustic emission, for structural health monitoring in engineering applications. The review …

To explore the mechanical properties and damage evolution characteristics of
carbonaceous shale with different confining pressures and water-bearing conditions, triaxial …

Foamed polymer is frequently used for waterproofing repairs in underground engineering.
Since the polymer acts as a plug in structure fractures, the mechanical characteristics of its …

The characterization of rock instability precursors and the identification of principal stress
direction are essential for the safety construction of underground engineering. This study …

Preexisting cracks are widely distributed in brittle rocks, and these cracks strongly influence
the rock failure mechanisms. The cracking process is accompanied by rapid energy release …
