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…

Passive viscous flow selection via fluid-induced buckling
Hemanshul Garg, Pier Giuseppe Ledda, Jon Skov Pedersen +1
We study the buckling of a clamped beam immersed in a creeping flow within a rectangular channel. Via a combination of precision experiments, simulations, and theoretical modeling,…
