Twisting instabilities in elastic ribbons with inhomogeneous pre-stress: a macroscopic analog of thermodynamic phase transition
Michael Gomez, Pedro M. Reis, Basile Audoly
We study elastic ribbons subject to large, tensile pre-stress confined to a central region within the cross-section. These ribbons can buckle spontaneously to form helical shapes,…
Delayed bifurcation in elastic snap-through instabilities
Mingchao Liu, Michael Gomez, Dominic Vella
We study elastic snap-through induced by a control parameter that evolves dynamically. In particular, we study an elastic arch subject to an end-shortening that evolves linearly wi…
Pull-in dynamics of overdamped microbeams
Michael Gomez, Dominic Vella, Derek E. Moulton
We study the dynamics of MEMS microbeams undergoing electrostatic pull-in. At DC voltages close to the pull-in voltage, experiments and numerical simulations have reported `bottlen…
Dynamics of viscoelastic snap-through
Michael Gomez, Derek E. Moulton, Dominic Vella
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 st…
Delayed pull-in transitions in overdamped MEMS devices
Michael Gomez, Derek E. Moulton, Dominic Vella
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…
Passive control of viscous flow via elastic snap-through
Michael Gomez, Derek E. Moulton, Dominic Vella
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 -…
