Abstract: E16.00001 : Smectic Description of Wrinkle Patterns*
8:00 AM–8:36 AM
In this talk I will show how an effective energy functional for the envelope of a wrinkle pattern emerges from coarse graining the elastic energy. I will point to the smectic-resembling terms in this effective energy functional, their impact and their geometry-induced interaction with the remaining terms that are associated with large-scale distortions. I will discuss how the variety of pattern motifs and transitions can be understood through their analogous liquid crystalline phases and phase transitions. I will demonstrate several possible applications of this new understanding of wrinkles.
