Faceted wrinkling at a contracted curved boundary : isometry and hysteretic wavelength selection

Thin elastic sheets are fascinating because they can show a rich variety of patterns and multi-scale physics from the interplay of only a few basic ingredients, viz., stretching, bending, and geometry. In this talk, through the behaviour of a simple system of a circular annulus contracted at the inner boundary, we will discuss two examples of how complexity can arise from simplicity. The first shows the emergence of macroscopic rigidity from a geometric constraint [1], and the second shows how large-scale structure is determined from small-scale units. This work represents the speaker's doctoral thesis, under the supervision of Prof. Tom Witten.
