Summary
A “symmetric impact” experiment was used as the basis for comparing different models of the fracture mechanism in granite. Two different tensile models were considered, but better results were obtained when both shear and tensile fracture were admitted. The combined model employs a fracture criterion based on static measurements of the tensile and triaxial compressive strength, and emphasizes the role of bulking which is related directly to the local rate of energy dissipation. It was shown that the behavior subsequent to incipient fracture has a major influence on the overall material response.
