Here we present an experimental and numerical investigation on the grain-scale geometrical and mechanical properties of partially crystallized structures made of macroscopic frictional grains. Crystallization is inevitable in arrangements of monosized hard spheres with packing densities exceeding Bernal's limiting density φBernal≈0.64. We study packings of monosized hard spheres whose density spans over a wide range (0.59<φ<0.72). These experiments harness x-ray computed tomography,...[Show more]
