Viscous adhesion in vibrated sheets: elastohydrodynamics with inertia and compressibility effects
Stephane Poulain, Timo Koch, L. Mahadevan +1
Inspired by recent experiments demonstrating that vibrating elastic sheets can function as seemingly contactless suction cups, we investigate the elastohydrodynamic hovering of a t…
