Progressive damage mechanism of rock-anchoring interface under cyclic impact loading

Abstract Cyclic impacts induce progressive fatigue damage at the rock–anchoring interface, thereby compromising the stability of deep roadway support systems. In this study, the split Hopkinson pressure bar and low-field nuclear magnetic resonance techniques were employed to investigate the macro- a...
