Fluid-induced snap-through instability of spherical shells
Pier Giuseppe Ledda, Hemanshul Garg, Vitus Østergaard-Clausen +3
We study the snapping instability of a spherical elastic shell induced by a viscous flow, the umbrella flipping problem when life is at low Reynolds numbers. We combine precision d…

Gravity-driven coatings on curved substrates: a differential geometry approach
Pier Giuseppe Ledda, Matteo Pezzulla, Etienne Jambon-Puillet +2
Although the drainage and spreading processes of thin liquid films on substrates have received growing attention during the last decades, the study of three-dimensional cases is li…
