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…
Customizing mesoscale self-assembly with 3D printing
M. Poty, G. Lumay, N. Vandewalle
Self-assembly due to capillary forces is a common method for generating 2D mesoscale structures from identical floating particles at the liquid-air interface. Designing building bl…
Breaking arches with vibrations: the role of defects
Celia Lozano, Geoffroy Lumay, Iker Zuriguel +1
We present experimental results about the stability of arches against external vibrations. Two dimensional strings of mutually stabilizing grains are geometrically analyzed and sub…
