Onset of mechanical stability in random packings of frictional spheres
Melissa Jerkins, Matthias Schröter, Harry L. Swinney +3
Using sedimentation to obtain precisely controlled packings of noncohesive spheres, we find that the volume fraction of the loosest mechanically stable packing is in…
The hierarchical properties of contact networks in granular packings
T. Aste, T. J. Senden
The topological structure resulting from the network of contacts between grains (contact network) is studied for very large samples of disorderly-packed monosized spheres with dens…
The Geometrical Structure of Disordered Sphere Packings
T. Aste, M. Saadatfar, T. J. Senden
The three dimensional structure of large packings of monosized spheres with volume fractions ranging between 0.58 and 0.64 has been studied with X-ray Computed Tomography. We searc…
X-ray observation of micro-failures in granular piles approaching an avalanche
Alexandre Kabla, Georges Debregeas, Jean-Marc Di Meglio +1
An X-ray imaging technique is used to probe the stability of 3-dimensional granular packs in a slowly rotating drum. Well before the surface reaches the avalanche angle, we observe…
