Evaluation of the short core in compression (SCC) method for measuring mode II fracture toughness of rocks

As a commonly ignored material property in materials science, the mode II fracture toughness is an important material parameter for rocks. The punch-through shear (PTS) method has been developed and accepted as the suggested method for measuring mode II fracture toughness of rocks by the International Society for Rock mechanics and Rock Engineering (ISRM). Because the PTS method involves complicated specimen preparation, the short core in...
