Disorder-induced stress-flow misalignment in soft glassy materials revealed using multi-directional shear
Frédéric Blanc, Guillaume Ovarlez, Adam Trigui +2
Controlling the mechanical response of soft glassy materials, such as emulsions, foams, and colloidal suspensions, is key for many industrial processes. While their steady-state fl…
Shear-thickening in presence of adhesive contact forces: the singularity of cornstarch
Anais Gauthier, Guillaume Ovarlez, Annie Colin
A number of dense particle suspensions experience a dramatic increase in viscosity with the shear stress, up to a solid-like response. This shear-thickening process is understood a…
X Radiography of Viscous Resuspension
Brice Saint-Michel, Sébastien Manneville, Steven Meeker +2
We use X-ray imaging to study viscous resuspension. In a Taylor-Couette geometry, we shear an initially settled layer of spherical glass particles immersed in a Newtonian fluid and…
Yielding and flow of foamed metakaolin pastes
Lucie Ducloué, Olivier Pitois, Laurent Tocquer +2
Metakaolin is a broadly used industrial raw material, with applications in the production of ceramics and geopolymers, and the partial replacement of Portland cement. The early sta…
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…
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…
