Avalanche precursors in a frictional model
Axelle Amon, Baptiste Blanc, Jean-Christophe Géminard
We present a one-dimensional numerical model based on elastically coupled sliders on a frictional incline of variable tilt. This very simple approach makes possible to study the pr…
Dynamics of crater formations in immersed granular materials
Germán Varas, Valérie Vidal, Jean-Christophe Géminard
We report the formation of a crater at the free surface of an immersed granular bed,locally crossed by an ascending gas flow. In two dimensions, the crater consists of two piles wh…
Creep motion of a granular pile induced by thermal cycling
Thibaut Divoux, Hervé Gayvallet, Jean-Christophe Géminard
We report a time-resolved study of the dynamics associated with the slow compaction of a granular column submitted to thermal cycles. The column height displays a complex behavior:…
