| We use molecular dynamics simulations of frictionless spherical particles to investigate a class of polydisperse granular materials in which the particle size distribution is uniform in particle volumes. The particles are assembled in a box by uniaxial compaction under the action of a constant stress. Due to the absence of friction and the nature of size distribution, the generated packings have the highest packing fraction at a given size span, defined as the ratio á of the largest size to the smallest size. We find that, up to á = 5, the packing fraction is a nearly linear function of á. While the coordination number is nearly constant due to the isostatic nature of the packings, we show that the connectivity of the particles evolves with á. In... |
