Experimental and Numerical Analysis of Mode I Fracture Process of Rock by Semi-Circular Bend Specimen
The semi-circular bend (SCB) specimen is widely used to measure fracture toughness of brittle materials such as rock. In this work, the stress field, fracture process zone (FPZ), and crack propagation velocity of SCB specimen are analyzed during the fracture process of rock specimens. The FPZ of spe...
