The Mesh and Height Effects of Rock Sample Failure in Uniaxial Compression by Statistical Damage Method

Due to presence of flaws in intact rock such as cracks and voids, rock failure associated with damage evolution becomes significantly discontinuous and difficult to describe. Based on the Weibull function and plastic criterion of Drucker–Prager, a statistical damage method has been implemented by finite element method. Laboratory testing has been conducted to verify in the method and to obtain the mechanical parameters of rock, which show good...
