Experimental Study on Rock Breaking Effect of Axe-Shaped and Triangular-Ridged Cutters Under Impact Load

In drilling engineering， optimized cutter selection for specific formations is critical to enhance rock breaking efficiency. To this end， a Split Hopkinson Pressure Bar （SHPB） apparatus was used to conduct impact-induced rock breaking tests of triangular-ridged and axe-shaped cutters under impact lo...
