... Abstract The Particle Flow Code (PFC), a numerical simulation code based on the distinct element method, is a useful tool for simulating the failure behavior of hard rocks. The introduction of clump logic (Cho et al., 2007) into the PFC modeling has made it possible for us to better reproduce...
