Elastocapillarity: When surface tension deforms elastic solids

Presented by:

Monday 18th September 2017 - 10:20 to 11:00
INI Seminar Room 1
Surface tension is usually associated with the spherical shape of small droplets and bubbles, wetting phenomena or the motion of insects at the surface of water. Beyond liquid interfaces, may capillary forces also affect solid bodies?
We propose review recent experiments where soft solids or slender structures are deformed by surface tension. We will focus in the following “elastocapillarity” configurations:
       - 3D, deformations induced in bulk solids
       - 1D, bending and bundling of rod-like structures 
       - 2D, bending and stretching of thin sheets

In each case, we will present the relevant characteristic lengths and scaling parameters.
