Rheology and microstructure of unsaturated granular materials: Experiments and simulations
M. Badetti, A. Fall, F. Chevoir +3
When dealing with unsaturated wet granular materials, a fundamental question is: what is the effect of capillary cohesion on the bulk flow and yield behavior? We inwestigate the de…
Shear strength of wet granular materials: macroscopic cohesion and effective stress
Michel Badetti, Abdoulaye Fall, François Chevoir +1
Rheometric measurements on assemblies of wet polystyrene bead assemblies, in steady uniform quasistatic shear flow, for varying liquid content within the small saturation (pendular…
Flow of wet granular materials: a numerical study
Saeed Khamseh, Jean-Noël Roux, François Chevoir
We simulate dense assemblies of frictional spherical grains in steady shear flow under controlled normal stress in the presence of a small amount of an interstitial liquid, whi…
Dry granular flows: rheological measurements of the -Rheology
Abdoulaye Fall, Guillaume Ovarlez, David Hautemayou +3
Granular materials do not flow homogeneously like fluids when submitted to external stress,but often form rigid regions that are separated by narrow shear bands where the material…
Shear flow of dense granular materials near smooth walls. I. Shear localization and constitutive laws in boundary region
Zahra Shojaaee, Jean-Noël Roux, François Chevoir +1
We report on a numerical study of the shear flow of a simple two-dimensional model of a granular material under controlled normal stress between two parallel smooth, frictional wal…
MRI investigation of granular interface rheology using a new cylinder shear apparatus
Pascal Moucheront, François Bertrand, Georg Koval +5
The rheology of granular materials near an interface is investigated through proton magnetic resonance imaging. A new cylinder shear apparatus has been inserted in the MRI device,…
