Séminaire PMMH – Florence Bertails-Descoubes (INRIA, Grenoble) & Sébastien Neukirch (∂Alembert)
Elastic Rods made easy with a Noether invariant
The static-dynamic analogy discovered by G. Kirchhoff shows that the statics of the planar elastica are equivalent to the dynamics of the pendulum. In this analogy, time and angular velocity are, for example, equivalent to arc length and curvatures.
This static-dynamic analogy allows us to write a quantity that is invariant along the elastic rod at equilibrium : A pendulum will have its mechanical energy constant in time and, in the same manner, a planar elastica will have the sum of its curvature energy and its axial force uniform along the structure.
We will show how this invariant may be used to quickly derive useful information on the equilibrium shapes of elastica in self-contact or in interaction with obstacles, sliding sleeves, force fields, and droplets.

The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
