Fluid-induced snap-through instability of spherical shells
Pier Giuseppe Ledda, Hemanshul Garg, Vitus Ãstergaard-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…
