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…
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…
How granular materials deform in quasistatic conditions
Jean-Noël Roux, Gaël Combe
Based on numerical simulations of quasistatic deformation of model granular materials, two rheological regimes are distinguished, according to whether macroscopic strains merely re…
Incremental response of granular materials: DEM results
Francesco Froiio, Jean-Noël Roux
We systematically investigate the incremental response of various equilibrium states of dense 2D model granular materials, along the biaxial compression path (σ11 < σ22, σ12 = 0).…
