AI Technical Summary
During rock fracture and damage, existing technologies struggle to accurately determine the wave velocity field changes and acoustic emission location of rock materials under quasi-static loading conditions, affecting the assessment of fracture and damage areas.
By fixing an acoustic emission probe on the surface of a rock sample, acoustic emission data and wave velocity matrix data are collected. Using the AST function of the acoustic emission monitoring device, the wave velocity matrix inside the sample is periodically recorded. The sample is then discretized, and the wave velocity field and acoustic emission location are iteratively calculated and inverted to determine the wave velocity field changes and acoustic emission location of the rock material.
It enables precise determination of wave velocity field changes and acoustic emission location in rock materials under quasi-static loading conditions, thereby improving the monitoring accuracy of fracture and damage areas.
