APPLICATIONS OF FINITE ELEMENT METHOD AND SIMULATION-BASED RELIABILITY ASSESSMENT METHOD FOR SOLUTIONS OF THE HARD ROCK DISINTEGRATION PROCESS
Original language description
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, reactionforces and fracture of the ore etc.) is solved via the FEM in combination with SBRA (Simulation- Based Reliability Assessment) Method (i.e. Monte Carlo simulations). The ore is disintegrated by deactivating the finite elements which satisfy the fracturecondition. Material of the ore (i.e. yield stress, fracture limit, etc.), is given by bounded histograms (i.e. stochastic inputs).However, it takes a long time to solve this problem (due to material and structural nonlinearities, the large number of elements, many Monte Carlo simulations, etc.). Hence, parallel computers were used to handle the large computational needs. Finally, the probabilistic reliability assessment is proposed.
