Buffering by buckling as a route for elastic deformation

D Vella - Nature Reviews Physics, 2019 - nature.com
Thin objects are deformed in a range of applications and at a range of scales, from
graphene and the actuators used in soft robots to the light sails of spacecraft. Such …

In-drop capillary spooling of spider capture thread inspires hybrid fibers with mixed solid–liquid mechanical properties

H Elettro, S Neukirch, F Vollrath… - Proceedings of the …, 2016 - National Acad Sciences
An essential element in the web-trap architecture, the capture silk spun by ecribellate orb
spiders consists of glue droplets sitting astride a silk filament. Mechanically this thread …

Elastocapillary bending of microfibers around liquid droplets

RD Schulman, A Porat, K Charlesworth, A Fortais… - Soft matter, 2017 - pubs.rsc.org
We report on the elastocapillary deformation of flexible microfibers in contact with liquid
droplets. A fiber is observed to bend more as the size of the contacting droplet is increased …

Liquid droplets act as “compass needles” for the stresses in a deformable membrane

RD Schulman, R Ledesma-Alonso, T Salez… - Physical Review Letters, 2017 - APS
We examine the shape of droplets atop deformable thin elastomeric films prepared with an
anisotropic tension. As the droplets generate a deformation in the taut film through capillary …

Auxiliary soft beam for the amplification of the elasto-capillary coiling: towards stretchable electronics

P Grandgeorge, A Antkowiak, S Neukirch - Advances in colloid and …, 2018 - Elsevier
A flexible fiber carrying a liquid drop may coil inside the drop thereby creating a drop-on-
fiber system with an ultra-extensible behavior. During compression, the excess fiber is …

Static wetting of a barrel-shaped droplet on a soft-layer-coated fiber

BX Zheng, C Pedersen, A Carlson, TS Chan - Soft Matter, 2023 - pubs.rsc.org
A droplet can deform a soft substrate due to capillary forces when they are in contact. We
study the static deformation of a soft solid layer coated on a rigid cylindrical fiber when an …

Growth of a flexible fibre in a deformable ring

A Cutolo, M Fraldi, G Napoli, G Puglisi - Soft Matter, 2023 - pubs.rsc.org
We study the equilibrium configurations related to the growth of an elastic fibre in a confining
flexible ring. This system represents a paradigm for a variety of biological, medical, and …

Elastocapillary coiling of an elastic rod inside a drop

H Elettro, P Grandgeorge, S Neukirch - Journal of Elasticity, 2017 - Springer
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 induced by …

Drop-on-coilable-fibre systems exhibit negative stiffness events and transitions in coiling morphology

H Elettro, F Vollrath, A Antkowiak, S Neukirch - Soft Matter, 2017 - pubs.rsc.org
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 drop-on …

Orb weaver glycoprotein is a smart biological material, capable of repeated adhesion cycles

SD Kelly, BD Opell, LL Owens - The Science of Nature, 2019 - Springer
Orb weavers produce webs that trap prey using a capture spiral formed of regularly spaced
glue droplets supported by protein fibers. Each droplet consists of an outer aqueous layer …
