Writhing and hockling instabilities in twisted elastic fibers

Autor: Adam Fortais, Elsie Loukiantchenko, Kari Dalnoki-Veress

Publikováno v: The European Physical Journal E. 44

The buckling and twisting of slender, elastic fibers is a deep and well-studied field. A slender elastic rod that is twisted with respect to a fixed end will spontaneously form a loop, or hockle, to relieve the torsional stress that builds. Further t

Spontaneous Elastocapillary Winding of Thin Elastic Fibers in Contact with Bubbles

Autor: Adam Fortais, Kari Dalnoki-Veress, Kathleen Charlesworth, Rafael D. Schulman

Publikováno v: Physical Review Letters. 127

We study the elastocapillary interaction between flexible microfibers in contact with bubbles trapped at the surface of a liquid bath. Microfibers placed on top of bubbles are found to migrate to and wrap into a coil around the perimeter of the bubbl

Liquid droplets on a free-standing glassy membrane: Deformation through the glass transition

Autor: Adam Fortais, Kari Dalnoki-Veress, Rafael D. Schulman

Publikováno v: The European Physical Journal E. 40

In this study, micro-droplets are placed on thin, glassy, free-standing films where the Laplace pressure of the droplet deforms the free-standing film, creating a bulge. The film's tension is modulated by changing temperature continuously from well b

Elastocapillary bending of microfibers around liquid droplets

Publikováno v: Soft Matter
Soft Matter, Royal Society of Chemistry, 2017, 13 (4), pp.720-724. ⟨10.1039/c6sm02095j⟩

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. At a critical droplet size, proportional to the bending elastoc
