Morphology-resolved stress contributions in sheared wet granular materials
Ahmad Awdi, Camille Chateau, Coumba Niang +3
Three-dimensional X-ray microtomography, coupled to rheometric measurements, enables a morphology-resolved reconstruction of capillary stresses at the grain scale in unsaturated we…
Unsaturated wet granular flows over a rough incline: frictional and cohesive rheology
Stephanie Deboeuf, Abdoulaye Fall
Multi-phase flows encountered in nature or in industry, exhibit non trivial rheological properties, that can be understood better thanks to model materials and appropriate rheomete…
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…
Optimal strengthening of particle-loaded liquid foams
François Gorlier, Yacine Khidas, Abdoulaye Fall +1
Foams made of complex fluids such as particle suspensions have a great potential for the development of advanced aerated materials. In this paper we study the rheological behavior…
Macroscopic Discontinuous Shear Thickening vs Local Shear Jamming in Cornstarch
A. Fall, F. Bertrand, D. Hautemayou +4
We study the emergence of discontinuous shear-thickening (DST) in cornstarch, by combining macroscopic rheometry with local Magnetic Resonance Imaging (MRI) measurements. We bring…
