Effect of rare events on out of equilibrium relaxation
Philippe Ribière, Patrick Richard, Renaud Delannay +3
This letter reports experimental and numerical results on particle dynamics in an out-of-equilibrium granular medium. We observed two distinct types of grain motion: the well known…

Experimental compaction of anisotropic granular media
Philippe Ribière, Patrick Richard, Daniel Bideau +1
We report on experiments to measure the temporal and spatial evolution of packing arrangements of anisotropic and weakly confined granular material, using high-resolution -ray a…

Importance of convection in the compaction mechanisms of anisotropic granular media
Philippe Ribiere, Patrick Richard, Renaud Delannay +1
We report the experimental observation of novel vortex patterns in a vertically tapped granular media. Depending on the tapping acceleration two behaviors are observed. For high ac…
