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…
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…
Analysis by x-ray microtomography of a granular packing undergoing compaction
Patrick Richard, Pierre Philippe, Fabrice Barbe +3
Several acquisitions of X-ray microtomography have been performed on a beads packing while it compacts under vertical vibrations. An image analysis allows to study the evolution of…
Energy Dissipation and Trapping of Particles Moving on a Rough Surface
C. Henrique, M. A. Aguirre, A. Calvo +4
We report an experimental, numerical and theoretical study of the motion of a ball on a rough inclined surface. The control parameters are , the diameter of the ball, , the i…
