Determination of Fracture Toughness of Anisotropic Rocks Under Water Vapour Pressure by Semi-Circular Bend Test
Failure of rock materials is a process of crack propagation. Crack initiation takes place when the crack tip stress intensity K reaches a critical value called fracture toughness, K1C. The rock fracture toughness is known to be affected by the surrounding environment such as temperature, confining...
