Abstract：The failure process of notched specimens with pre-existed cracks or hard granules under external tensile loading are simulated with RFPA2D(Rock Failure Process Analysis)code. The influence of different heterogeneity on the coalescence of cracks and the load-displacement curve is analyzed. The simulating results indicate that it is the local stress concentration and deformation localization due to the heterogeneity that causes the complex interaction of cracks and different patterns of propagation and coalescence.
