Dynamic Rearrangements and Packing Regimes in Randomly Deposited Two-Dimensional Granular Beds
I. Bratberg, F. Radjai, A. Hansen
We study the structural properties of two-dimensional granular packings prepared by random deposition from a source line. We consider a class of random ballistic deposition models…
Pre-avalanche instabilities in a granular pile
Lydie Staron, Jean-Pierre Vilotte, Farhang Radjai
We investigate numerically the transition between static equilibrium and dynamic surface flow of a 2D cohesionless granular system driven by a continuous gravity loading. This tran…
Turbulent-like fluctuations in quasistatic flow of granular media
F. Radjai, S. Roux
We analyze particle velocity fluctuations in a simulated granular system subjected to homogeneous quasistatic shearing. We show that these fluctuations share the following scaling…
A Model for Granular Texture with Steric Exclusion
H. Troadec, F. Radjai, S. Roux +1
We propose a new method to characterize the geometrical texture of a granular packing at the particle scale including the steric hindrance effect. This method is based on the assum…
