Abstract

Using DEM (Discrete Element Method), a model is presented for simulation of breakage of two-dimensional polygon-shaped particles. In this model, shapes of the particles generated after breakage are predefined and each uniform (uncracked) particle is replaced with some smaller inter-connected sub-particles. If the bond between these sub-particles break, breakage will happen. With the help of this model, it is possible to study the influence of particle breakage on internal angle of friction and deformability of granular materials. For this purpose, two series of biaxial test simulations (breakage is enabled and disabled) are conducted on assemblies of two-dimensional polygon-shaped particles with different confining pressures and the results are compared. It was found that the simulation results are in good agreement with observations obtained from experimental tests.
