Viscoelasticity Enhances Contactless Adhesion of Soft Substrates
Marco Rizzo, Jacco H. Snoeijer, Vincent Bertin +1
Understanding adhesion is essential for describing stability, friction, and interfacial dynamics. Here, we investigate the adhesion force dynamics between a rigid sphere and a soft…
Transition from contact to hydrodynamic lubrication over rough surfaces
Vincent Bertin, Olivier Pouliquen
We present a theoretical analysis of frictional transitions along the Stribeck curve for rough elastic contacts lubricated by a Newtonian fluid. Building on the mean-field framewor…
Viscoelastic lubrication of a submerged cylinder sliding down an incline
Alexandros T. Oratis, Kai van den Berg, Vincent Bertin +1
Lubrication flows between two solid surfaces can be found in a variety of biological and engineering settings. In many of these systems, the lubricant exhibits viscoelastic propert…
Sticking without contact: Elastohydrodynamic adhesion
Vincent Bertin, Alexandros T. Oratis, Jacco H. Snoeijer
The adhesion between dry solid surfaces is typically governed by contact forces, involving surface forces and elasticity. For surfaces immersed in a fluid, out-of-contact adhesion…
Viscoelastic wetting transition: beyond lubrication theory
Minkush Kansal, Charu Datt, Vincent Bertin +1
The dip-coating geometry, where a solid plate is withdrawn from or plunged into a liquid pool, offers a prototypical example of wetting flows involving contact-line motion. Such fl…
