Description	Rock Failure Process Analysis code, RFPA2D, is used to simulate the crack propagation path and the failure process of a specimen containing pre-existing crack. Based on the simulation results, the influence of heterogeneity on crack propagation mode is studied. The numerical simulation reproduces the phenomenon of the evolution of the stress and strain fields in the process of crack propagation. The phenomena of acoustic emissions related to the heterogeneity of rock and the rock bridge related to the non-persistent feature of cracks are also modelled. The difference in crack propagation path has been found between heterogeneous and homogeneous specimens. In homogeneous specimen, the crack propagation path is smooth and persistent comparing with the heterogeneous specimen.
