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 fraction, varying between 6.9 and 8.2 for packing fractions between 0.59 and 0.64.Keywords: Average coordination number; Coordination number; Deconvolution techniques; Monodisperse; Monodisperse spheres; Packing fractions; Three-dimensional structure; Tomographic images; X-ray computed tomography; X-ray tomography; Micromechanics; Powders; Spher20052016-02-24
