Contact mechanics and friction of soft materials: an apparatus combining multi-axes dynamical actuation/measurement and in situ/in operando visualisation
Matthieu Guibert, Antoine Aymard, Cristobal Oliver +8
The mechanics and friction of contact interfaces involving soft materials like gel, rubber or human skin are of both fundamental and applied interest. Recent insights have been mad…
Colloidal Suspensions can have Non-Zero Angles of Repose below the Minimal Value for Athermal Frictionless Particles
Jesús Fernández, Loïc Vanel, Antoine Bérut
We investigate the angle of repose of dense suspensions of colloidal silica particles ( to ) in water-filled microfluidic rotating drum experiments, to pr…
Capillary and priming pressures control the penetration of yield-stress fluids through non-wetting 2D meshes
Manon Bourgade, Nicolas Bain, Loïc Vanel +2
Forcing hydrophilic fluids through hydrophobic porous solids is a recurrent industrial challenge. If the penetrating fluid is Newtonian, the imposed pressure has to overcome the ca…
Aging in the Flow Dynamics of Dense Suspensions of Contactless Microparticles
Jesús Fernández, Loïc Vanel, Antoine Bérut
This study demonstrates that the free-surface flow dynamics of dense piles of contactless silica microparticles depend on the resting period prior to flow. Microfluidic rotating dr…
Load-Dependent Power-Law Exponent in Creep Rupture of Heterogeneous Materials
Chloé Braux, Antoine Bérut, Loïc Vanel
Creep tests on heterogeneous materials under subcritical loading typically show a power-law decaying strain rate before failure, with the exponent often considered material-depende…
