The meso-fracturing mechanism of marble under unloading confining pressure paths and constant axial stress

Abstract Failure tests on marble during unloading confining-pressure under constant axial stress and simulations with the particle flow code were performed. The influence mechanism of the unloading rate of the confining pressure, initial unloading stress, and confining pressure on the failure charac...
