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,…
Yield stress and shear-banding in granular suspensions
Abdoulaye Fall, Francois Bertrand, Guillaume Ovarlez +1
We study the emergence of a yield stress in dense suspensions of non-Brownian particles, by combining local velocity and concentration measurements using Magnetic Resonance Imaging…
Damage due to salt crystallization in porous media
Noushine Shahidzadeh Bonn, Francois Bertrand, Daniel Bonn
We investigate salt crystallization in porous media that can lead to their disintegration. For sodium sulfate we show for the first time experimentally that when anhydrous crystals…
