Bending-damaged fracture criterion and numerical implementation of limestone beam under three-point bending test

Frontiers in Earth Science, 2023
To study the characteristics of tensile cracking by rock-bending damage, the bending stress–strain curves and the cumulative ringing counts were obtained by a three-point bending test and acoustic emission (AE) monitoring of limestone beams. Based on the
