Local and global relations between the number of contacts and density in monodisperse sphere packs

Aste, Tomaso; Saadatfar, Mohammad; Senden, Tim J.


The topological structure resulting from the network of contacts between grains (contact network) is studied for large samples of monosized spheres with densities (fraction of volume occupied by the spheres) ranging from 0.59 to 0.64. We retrieve the coordinates of each bead in the pack and we calculate the average coordination number by using three different methods. We show that, in the range of density investigated, the coordination number is larger than four and it increases with the...[Show more]
