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…

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…
