A modified particle contact model for matching the ratios of uniaxial compressive to tensile strength of brittle rocks

Abstract The Hertz-Mindlin with bonding (HMB) contact model in the commercial discrete element method (DEM) software EDEM is widely used to simulate and analyze the mechanical behavior of rocks. However, it cannot match the high ratios of uniaxial compressive strength (UCS) to tensile strength (TS)...
