Stretching the limits of dynamic and quasi-static flow testing on limestone powders
Hao Shi, Geoffroy Lumay, Stefan Luding
Powders are a special class of granular matter due to the important role of cohesive forces. The flow behavior of powders depends on the flow states and stress and is therefore dif…
Magnetoelastic instability in soft thin films
M. Poty, F. Weyer, G. Grosjean +2
Ferromagnetic particles are incorporated in a thin soft elastic matrix. A lamella, made of this smart material, is studied experimentally and modeled. We show herein that thin film…
Flow of magnetic repelling grains in a two-dimensional silo
G. Lumay, J. Schockmel, D. Henández-Enríquez +3
During a typical silo discharge, the material flow rate is determined by the contact forces between the grains. Here, we report an original study concerning the discharge of a two-…
Statics and dynamics of magnetocapillary bonds
Guillaume Lagubeau, Galien Grosjean, Alexis Darras +3
When ferromagnetic particles are suspended at an interface under magnetic fields, dipole-dipole interactions compete with capillary attraction. This combination of forces has recen…
Remote control of self-assembled microswimmers
Galien Grosjean, Guillaume Lagubeau, Alexis Darras +3
Physics governing the locomotion of microorganisms and other microsystems is dominated by viscous damping. An effective swimming strategy involves the non-reciprocal and periodic d…
Toward Bernal Random Loose Packing through freeze-thaw cycling
F. Ludewig, N. Vandewalle, S. Dorbolo +2
We study the effect of freeze-thaw cycling on the packing fraction of equal spheres immersed in water. The water located between the grains experiences a dilatation during freezing…
