Abstract: The DEM simulation was conducted to investigate the jamming transition of bidisperse disk assemblies under isotropic compression, and the effect of friction on the critical jammed states was mainly discussed. As the friction coefficient increases, the packing fraction and the average contact number decrease; the difference between mechanical and geometrical average contact number increases; and the percentage of particles which have different contact numbers also varies with friction. According to the numerical results, the critical jammed states got from zero and infinite friction coefficient are isostatical packing, and the packing fraction shows a linear correlation with mechanical average contact number at J point.

Key words: granular systems, critical jammed states, volume fraction, average contact number
