Progressive friction mobilization and enhanced Janssen's screening in confined granular rafts
Oscar V. Saavedra, Hervé Elettro, Francisco Melo
Confined two-dimensional assemblies of floating particles, known as granular rafts, are prone to develop a highly nonlinear response under compression. Here we investigate the tran…
The heavy windlass: Buckling and coiling of an elastic rod inside a liquid drop in the presence of gravity
Hervé Elettro, Arnaud Antkowiak, Sébastien Neukirch
A liquid drop sitting on an elastic rod may act as a winch, or windlass, and pull the rod inside itself and coil it. This windlass effect has been shown to be generated by surface…
Converting water adsorption and capillary condensation in useable forces with simple porous inorganic thin films
Mickael Boudot, Hervé Elettro, David Grosso
This work reports an innovative humidity driven actuation concept based on Bangham effect using simple nanoporous sol-gel silica thin films as humidity responsive materials. Bilaye…
Coiling of an elastic beam inside a disk: A model for spider-capture silk
Hervé Elettro, Fritz Vollrath, Sébastien Neukirch +1
Motivated by recent experimental observations of capillary-induced spooling of fibers inside droplets both in spider capture silk and in synthetic systems, we investigate the behav…
Elastocapillary coiling of an elastic rod inside a drop
Hervé Elettro, Paul Grandgeorge, Sébastien Neukirch
Capillary forces acting at the surface of a liquid drop can be strong enough to deform small objects and recent studies have provided several examples of elastic instabilities indu…
Drop-on-coilable-fibre systems exhibit negative stiffness events and transitions in coiling morphology
Hervé Elettro, Sébastien Neukirch, Fritz Vollrath +1
We investigate the mechanics of elastic fibres carrying liquid droplets. In such systems, buckling may localize inside the drop cavity if the fibre is thin enough. This so-called d…
