Memory effects in friction: the role of sliding heterogeneities
vincenzo Fazio, Vito Acito, Fabien Amiot +2
We report on memory effects involved in the transient frictional response of a contact interface between a silicone rubber and a spherical glass probe when it is perturbed by chang…
Straightforward measurement of thermal properties of anisotropic materials: the case of Bi2Se3 single crystal
Danièle Fournier, Massimiliano Marangolo, Mahmoud Eddrief +2
We show that by a simple two-steps measurement protocol one can extract the thermal properties of anisotropic insulator materials. We focus on Bi2Se3 single crystal, a layered crys…
Experimental investigation of water distribution in two-phase zone during gravity-dominated evaporation
C. Cejas, J. -C. Castaing, L. A. Hough +2
We characterize the water repartition within the partially saturated (two-phase) zone (PSZ) during evaporation out of mixed wettable porous media by controlling the wettability of…
Effects of stretching on the frictional stress of rubber
Antoine Chateauminois, Danh-Toan Nguyen, Christian Frétigny
In this paper, we report on new experimental results on the effects of in-plane surface stretching on the friction of Poly(DiMethylSiloxane) (PDMS) rubber with smooth rigid probes.…
Contact of a spherical probe with a stretched rubber substrate
Christian Fretigny, Antoine Chateauminois
We report on a theoretical and experimental investigation of the normal contact of stretched neo-Hookean substrates with rigid spherical probes. Starting from a published formulati…
Multiscale Surface-Attached Hydrogel Thin Films with Tailored Architecture
Benjamin Chollet, Mengxing Li, Ekkachai Martwong +4
A facile route for the fabrication of surface-attached hydrogel thin films with well-controlled chemistry and tailored architecture on wide range of thickness from nanometers to mi…
Friction of viscoelastic elastomers with rough surfaces under torsional contact conditions
M. Trejo, C. Frétigny, A. Chateauminois
Frictional properties of contacts between a smooth viscoelastic rubber and rigid surfaces are investigated using a torsional contact configuration where a glass lens is continuousl…
Non-Amontons-Coulomb local friction law of randomly rough contact interfaces with rubber
D. T. Nguyen, E. Wandersman, A. Prevost +3
We report on measurements of the local friction law at a multi-contact interface formed between a smooth rubber and statistically rough glass lenses, under steady state friction. U…
Effect of geometry on the dewetting of granular chains by evaporation
Cesare M. Cejas, Lawrence A. Hough, Christian Frétigny +1
Understanding evaporation or drying in granular media still remains complex despite recent advancements. Evaporation depends on liquid transport across a connected film network fro…
A Simple Analytical Model of Evaporation in the Presence of Roots
Cesare M. Cejas, Larry Hough, Jean-Christophe Castaing +2
Root systems can influence the dynamics of evapotranspiration of water out of a porous medium. The coupling of evapotranspiration remains a key aspect affecting overall root behavi…
Kinetics of Gravity-Driven Water Channels Under Steady Rainfall
Cesare M. Cejas, Yuli Wei, Remi Barrois +3
We investigate the formation of fingered flow in dry granular media under simulated rainfall using a quasi-2D experimental set-up composed of a random close packing of mono-dispers…
Probing thermal waves on the free surface of various media: Surface Fluctuation Specular Reflection Spectroscopy
Astrid Tay, Caroline Thibierge, Danièle Fournier +5
Thermal motion gives rise to fluctuations in free surfaces; the propagation of the thermally excited waves on such surfaces depends on the mechanical properties of the medium. Thei…
