Séminaire PMMH - Joseph Paulsen (Syracuse University)

Vendredi 8 avril 2016 de 11h00 à 12h00 - Bureau d'Etudes

The wavelength of wrinkles in elastic sheets on curved topographies

A thin elastic sheet will buckle when it is compressed, leading to the familiar wrinkle patterns on our foreheads, on plastic-wrapped objects, and on crinkly leaves. Wrinkling has recently been used as a noninvasive probe of thin film properties and mechanical environment. However, the current understanding of wrinkle wavelength is limited to parallel undulations on flat topographies. We propose a local law for wavelength that extends to spatially-varying wrinkle patterns in curved settings. We find excellent agreement with our experiments on thin polymer films floating on curved liquid surfaces.

Information for the speakers

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.
