Finally, a series of triaxial compression tests are performed on simulated specimens with cement content of 2% under three confining pressures, and the DEM results are compared and analyzed. Second, the bond contact model is implemented into the 3-D DEM software (PFC 3D), and verified by simulating tension, compression and shear tests on two spherical balls.
First, according to the mechanical behaviors and existence conditions of bond materials, this model is established by simplifying the contact behaviors of two aluminum rods glued together by cement.
