The geometry and the number of contacts on monodisperse sphere packs using X-ray tomography

Saadatfar, Mohammad; Kabla, A; Senden, Timothy; Aste, Tomaso


The three-dimensional structure of very large samples of monodisperse bead packs is studied by means of X-Ray Computed Tomography. We retrieve the coordinatesofeach bead inthe pack and wecalculate the average coordination number by using the tomographic images to single out the neighbors in contact. The results are compared with the average coordination number obtained in Aste et al. (2005) by using a deconvolution technique. We show that the coordination number increases with the packing...[Show more]
