Abstract

Using sedimentation to obtain precisely controlled packings of noncohesive spheres, we find that the volume fraction phi(RLP) of the loosest mechanically stable packing is in an operational sense well defined by a limit process. This random loose packing volume fraction decreases with decreasing pressure p and increasing interparticle friction coefficient mu. Using x-ray tomography to correct for a container boundary effect that depends on particle size, we find for rough particles in the limit p -> 0 a new lower bound, phi(RLP)=0.550 +/- 0.001.
