摘要：Numerical approach is useful for simulating the rock failure behavior under various stress fields and the effects of various rock parameters. In order to simulate fracture process of inhomogeneous rock specimen in meso-scale under uniaxial compression test, a new numerical simulation procedure based on finite element method is proposed. The simulation procedure is based on Mohr-Coulomb fracture criterion. Taking rock specimen as inhomogeneous and quasi-brittle material, the shear strength parameters of rock element are subjected to normal distribution. The FEM analysis investigation shows that inhomogeneity of rock specimen has a significant influence on the simulated stress-strain curve and the simulated curve agrees well with the experimental curve. ? 2015 ejge.
