Abstract

This paper presents Monte Carlo simulations to study the density relaxation process in monodisperse granular materials, in which the effect of discrete taps on the system is modeled by applying normalized vertical lifts of intensity δ/d to the assembly. Examination of the bulk densities over a wide range of lift intensities suggests the existence of a critical value that optimizes the evolution of the density. Furthermore, the 'evolution' of the distribution of particles along the depth reveals an upward progression of organized layers that are induced by the plane floor. Results of ongoing discrete element simulations (presented elsewhere) provide strong support for this finding.
