Dynamics of viscoelastic snap-through
Abstract We study the dynamics of snap-through when viscoelastic effects are present. To gain analytical insight we analyse a modified form of the Mises truss, a single-degree-of-freedom structure,Expand

Ghosts and bottlenecks in elastic snap-through
Snap-through is a striking instability in which an elastic object rapidly jumps from one state to another. It is seen in the leaves of the Venus flytrap plant and umbrellas flipping on a windy dayExpand

Critical slowing down in purely elastic 'snap-through' instabilities
Critical phenomena are well understood in a wide range of physical systems. The dynamics of snap-through instabilities, a widespread phenomenon in their own right, are now shown to display criticalExpand

Passive Control of Viscous Flow via Elastic Snap-Through.
We demonstrate the passive control of viscous flow in a channel by using an elastic arch embedded in the flow. Depending on the fluid flux, the arch may "snap" between two states-constricting andExpand

The shallow shell approach to Pogorelov's problem and the breakdown of ‘mirror buckling’
We present a detailed asymptotic analysis of the point indentation of an unpressurized, spherical elastic shell. Previous analyses of this classic problem have assumed that for sufficiently largeExpand

Skill of ensemble flood inundation forecasts at short- to medium-range timescales
Abstract We investigate the ability to improve flood inundation forecasts at short- to medium-range (1–7 days) timescales through weather ensembles and statistical water surface elevation (WSE)Expand

Scanning and modeling for non-standard edge geometry endmills
Abstract This paper describes a reverse engineering solution for modeling the behavior of non-standard edge geometry endmills. Structured light scanning is used to produce a solid model of theExpand

Delayed pull-in transitions in overdamped MEMS devices
We consider the dynamics of overdamped MEMS devices undergoing the pull-in instability. Numerous previous experiments and numerical simulations have shown a significant increase in the pull-in timeExpand
