Marisa did a really great work. Congratulations !!
Our paper on the “Curvature-induced symmetry breaking determines elastic surface patterns” has just been published online in Nature Materials !
The wrinkling morphologies of our curved elastic bilayer materials are further analyzed in collaboration with a team from the Math department of MIT. The pattern formation is described here by deriving a generalized Swift-Hohenberg theory. This theory, universally applicable to macroscopic and microscopic systems, can be extend to arbitrarily shaped surfaces, thereby solving a longstanding problem in elasticity theory.
Our paper on the “Wrinkling crystallography on spherical surfaces” has just been published in PNAS !
Curved crystals cannot comprise hexagons alone; additional defects are required by both topology and energetics that depend on the system size. Treating dimples, generated through curved wrinkling, as point-like packing units, we show that our system can be mapped into and described within the framework of curved crystallography, albeit with some important differences attributed to the far-from-equilibrium nature of our patterns.
