Experimental and numerical investigations on the tensile
In recent years with the split Hopkinson pressure bar SHPB system the study on mechanical properties of rocks subjected to multiple impacts has received more and more attention [14] [15] [16] [17] Researchers found that the dynamic damage caused by a single impact is relatively small when the incident stress drops to the range from 60% to 70% of the
