Moving out of plane: wrinkling and buckling

Thin structures typically buckle out of plane when compressed, giving rise to a myriad of shapes. These range from classic Euler buckling to honey coiling to microscale wrinkling patterns, and can occur in both fluid and solid systems. Some of these situations correspond to a ``failure'', but others may be exploited for applications such as flexible electronics.

In this talk I will introduce some examples of buckling and wrinkling mechanisms, discussing their uses and the corresponding challenges. I will introduce mathematical models for addressing these challenges, discussing the new insights gained and some open questions.
