Column collapse of granular rods.
We investigate the collapse of granular rodpiles as a function of particle (length/diameter) and pile (height/radius) aspect ratio. We find that, for all particle aspect ratios below 24, there exists a critical height Hl below which the pile never collapses, maintaining its initial shape as a solid, and a second height Hu above which the pile always collapses. Intermediate heights between Hl an...

متن کاملWet granular materials
Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many industrial applications), liquid is present between the grains. This produces inter-grain cohesion and drastically modifies the mechanical proper...

174 nature materials | VOL 7 | MARCH 2008 | www.nature.com/naturematerials will evaluate the biodistribution of labelled nanoparticles in compartments outside of the joint space. This may better illustrate the routes of clearance from the joint, be they lymphatic or vascular, as well as indicate the functional residence times of the drugs in the tissue. In addition, erosion and proteolysis of t...
متن کاملFlow of wet granular materials.
The transition from frictional to lubricated flows of a dense suspension of non-Brownian particles is studied. The pertinent parameter characterizing this transition is the Leighton number Le=eta(s)gamma / sigma, the ratio of lubrication to frictional forces. Le defines a critical shear rate below which no steady flow without localization exists. In the frictional regime the shear flow is local...
