Unjamming a granular hopper by vibration
A. Janda, D. Maza, A. Garcimartin +3
We present an experimental study of the outflow of a hopper continuously vibrated by a piezoelectric device. Outpouring of grains can be achieved for apertures much below the usual…
Spreading of a granular droplet
Ivan Sanchez, Franck Raynaud, Jose Lanuza +3
The influence of controlled vibrations on the granular rheology is investigated in a specifically designed experiment. We study experimentally a thin granular film spreading under…
Compaction and mobility in randomly agitated granular assemblies
G. Caballero, J. Lanuza, E. Clement
We study the compaction and mobility properties of a dense granular material under weak random vibration. By putting in direct contact millimetric glass beads with piezoelectric tr…
Dynamic and instability of submarine avalanches
F. Malloggi, J. Lanuza, B. Andreotti +1
We perform a laboratory-scale experiment of submarine avalanches on a rough inclined plane. A sediment layer is prepared and thereafter tilted up to an angle lower than the spontan…
Experiments in randomly agitated granular assemblies close to the jamming transition
G. Caballero, A. Lindner, G. Ovarlez +3
We present here the preliminary results obtained for two experiments on randomly agitated granular assemblies using a novel way of shaking. First we discuss the transport propertie…
Reorganization of a dense granular assembly: the `unjamming response function'
E. Kolb, J. Cviklinski, J. Lanuza +2
We investigate the mechanical properties of a static dense granular assembly in response to a local forcing. To this end, a small cyclic displacement is applied on a grain in the b…
