Mechanical characterization of partially crystallized sphere packings

Hanifpour, M; Francois, Nicolas; Allaei, Mehdi; Senden, Timothy; Saadatfar, Mohammad


We study grain-scale mechanical and geometrical features of partially crystallized packings of frictional spheres, produced experimentally by a vibrational protocol. By combining x-ray computed tomography, 3D image analysis, and discrete element method simulations, we have access to the 3D structure of internal forces. We investigate how the network of mechanical contacts and intergranular forces change when the packing structure evolves from amorphous to near perfect crystalline arrangements....[Show more]
