Crack Initiation Behaviors of Granite Specimens Containing Crossing‐Double‐Flaws with Different Lengths under Uniaxial Loading

Crack initiation is an important stage in the failure process of rock masses. In this paper, crack initiation behaviors (crack initiation model, crack initiation location, crack initiation angle, and crack initiation stress) of granite specimens containing crossing‐double‐flaws with different lengths were investigated using PFC2 D software. Crack initiation models were all tensile wing cracks, which did not exactly initiate from the main flaw...
