Elastic medium confined in a column versus the Janssen experiment
G. Ovarlez, E. Clément
We compute the stresses in an elastic medium confined in a vertical column, when the material is at the Coulomb threshold everywhere at the walls. Simulations are performed in 2 di…
Flow of wet granular materials
N. Huang, G. Ovarlez, F. Bertrand +3
The transition from frictional to lubricated flow of a dense suspension of non-Brownian particles is studied. The pertinent parameter characterizing this transition is the Leighton…
Nonlinear instability of density-independent orbital-free kinetic energy functionals
X. Blanc, E. Cances
We study in this article the mathematical properties of a class of orbital-free kinetic energy functionals. We prove that these models are linearly stable but nonlinearly unstable,…
Elastic wave propagation in confined granular systems
Ellak Somfai, Jean-Noel Roux, Jacco H. Snoeijer +2
We present numerical simulations of acoustic wave propagation in confined granular systems consisting of particles interacting with the three-dimensional Hertz-Mindlin force law. T…
