Friction vs Texture at the Approach of a Granular Avalanche
Lydie Staron, Farhang Radjai
We perform a novel analysis of the granular texture of a granular bed close to stability limit. Our analysis is based on a unique criterion of friction mobilisation in a simulated…

Study of the collapse of granular columns using DEM numerical simulation
L. Staron, E. J. Hinch
Numerical simulations of the collapse and spreading of granular columns onto an horizontal plane using the Contact Dynamics method are presented. The final shape of the deposit see…

Multiscale Analysis of the Stress State in a Granular Slope in Transition to Failure
Lydie Staron, Jean-Pierre Vilotte, Farhang Radjai
By means of contact dynamics simulations, we analyze the stress state in a granular bed slowly tilted towards its angle of repose. An increasingly large number of grains are overlo…
