Séminaire PMMH - Eric Dufresne (ETH, Zurich)
Three-Phase Contacts with Soft Solid Substrates
Surface forces can drive large deformations of soft solids. I will discuss the deformation of soft solids in contact with liquid droplets and rigid particles. Here, classic results for wetting and adhesion fail to describe the equilibrium of three-phase contact lines. While interfacial energies are sufficient to describe wetting and adhesion on stiffer solids, we find that surface stresses play a central role in contact problems with soft solids. The surface stress of a liquid droplet is simply the familiar, isotropic, and strain-independent surface tension. However, the surface stress of a solid is generally more complex. I will show that even gels, which have a large fluid fraction, can demonstrate strain-dependent anisotropic surface stresses.

Séminaire PMMH - Salvatore Federico (University of Calgary, Canada)
Vendredi 4 juillet de 11h00 à 12h00 - Salle réunion PMMH 1
Continuum Mechanics of Hydrated Fibre-Reinforced Soft Tissues
Biological tissues can be represented as bi-phasic continua, with a porous solid phase saturated by an interstitial fluid and reinforced by collagen fibers. This lecture will give an overview of the modelling techniques for fibre-reinforced porous composite materials with statistical orientation of the fibers. Both (…) -

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
