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…
