Annotation
This paper focuses on a numerical analysis of the hard rock (ore) disintegration process. The bit moves into the ore (i.e. mechanical contact with friction) and subsequently disintegrates it. The disintegration (i.e. stress-strain relationship, reaction forces and fracture of the ore etc.) is solved via the FEM in combination with SBRA (Simulation-Based Reliability Assessment) Method. The ore is disintegrated by deactivating the FE which satisfy the fracture condition. Material of the ore (i.e. yield stress, fracture limit, etc.), is given by stochastic inputs. The results are compared with experiments.
