Effect of the Preexisting Fissure with Different Fillings in PMMA on Blast-Induced Crack Propagation
In order to study the dynamic crack propagation law in fissured rock under the different fillings, a borehole with 7 mm diameter was processed in the center of a polymethyl methacrylate (PMMA) specimen. The preexisting fissure with different angles (θ = 0°, 45°, and 90°) and different distances (L =...
