# Shape of an elastic loop strongly bent by surface tension: experiments and comparison with theory.

@article{Mora2012ShapeOA, title={Shape of an elastic loop strongly bent by surface tension: experiments and comparison with theory.}, author={Serge Mora and Ty Phou and Jean-Marc Fromental and Basile Audoly and Yves Pomeau}, journal={Physical review.

When a very flexible wire is dipped into a soapy solution, it collapses onto itself. We consider the regions of high curvature where the wire folds back onto itself, enclosing a capillary film. The shapes of these end loops are measured in experiments using soap films and compared to a known similarity solution. The sizes of these structures provide a simple and reliable way to measure surface tension.

This work defines an energy associated with shape deformations of the system and derives general equilibrium and (linear) stability conditions by considering the first and second variations of the energy functional, and finds that the presence of intrinsic curvature is necessary to obtain a first buckling mode which is not purely tangent to the spanning surface.
