Discrete Element Modeling of Crack Initiation Stress of Marble Based on Griffith’s Strength Theory
Investigating the crack initiation stress of rocks is vital for understanding the gradual damage process of rocks and the evolution law of internal cracks. In this paper, the particle flow code method is used to conduct biaxial compression tests on a marble model with an elliptical crack under diffe...
