Investigation of failure mode and shear strength of rock joints using discrete element method

Shear failure mode and strength of artificial rock joints are studied under different levels of joint compression. A quasi-static discrete element modeling is presented that reproduces the brittle material as a dense assemblage of deformable triangular particles. Using this, plaster-made samples with saw-tooth asperities are modeled and numerical results are compared with experimental measurement. The investigation approves that the proposed DEM is successful of predicting shear response of rock joints.
