Experimental study of hybrid crack of coal-measure rocks with image and acoustic emission monitoring using SCB method
Most instability damage in rock engineering results from the accumulation of microcracks. Fracture tests were conducted in I/II mixed mode using semi-circular bending (SCB) Specimens comprising coal, sandy mudstone, and sandstone with five different pre-fracture angles ( β ). The evolution of fractu...
