How much energy does it take to stamp a thin elastic shell flat? Motivated by recent experiments on the wrinkling patterns of floating shells, we develop rigorous method via $\Gamma$-convergence for answering this question leading order in shell's thickness and other small parameters. The observed involve "ordered" regions well-defined wrinkles alongside "disordered" whose local features are le...

The applications of membranes are increasing rapidly in various fields of engineering and science. The geometric, material, force and contact non-linearities complicate their analysis, which increases the demand for computationally efficient methods and interpretation of counter-intuitive behaviours. To understand the complex behaviour of membrane structures, it is necessary to perform parametr...

A numerical study of 3D droplets active matter reveals many dynamical responses to a microscopic influx energy, such as fingerlike protrusions and surface wrinkling, offering new physics insight into life sciences.
