A comparative analysis of numerical approaches to the mechanics of elastic sheets
Michael Taylor, Benny Davidovitch, Zhanlong Qiu +1
Numerically simulating deformations in thin elastic sheets is a challenging problem in computational mechanics due to destabilizing compressive stresses that result in wrinkling. D…
A sheet on deformable sphere: "wrinklogami" patterns suppress curvature-induced delamination
Evan Hohlfeld, Benny Davidovitch
The adhesion of a stiff film onto a curved substrate often generates elastic stresses in the film that eventually give rise to its delamination. Here we predict that delamination o…
Indentation of ultrathin elastic films and the emergence of asymptotic isometry
Dominic Vella, Jiangshui Huang, Narayanan Menon +2
We study the indentation of a thin elastic film floating at the surface of a liquid. We focus on the onset of radial wrinkles at a threshold indentation depth and the evolution of…
Mechanics of large folds in thin interfacial films
Vincent Démery, Benny Davidovitch, Christian D. Santangelo
A thin film at a liquid interface responds to uniaxial confinement by wrinkling and then by folding; its shape and energy have been computed exactly before self contact. Here, we a…
Roadmap to the morphological instabilities of a stretched twisted ribbon
Julien Chopin, Vincent Démery, Benny Davidovitch
We address the mechanics of an elastic ribbon subjected to twist and tensile load. Motivated by the classical work of Green and a recent experiment that discovered a plethora of mo…
