Autonomous, untethered gait-like synchronization of lobed loops made from liquid crystal elastomer fibers via spontaneous snap-through
The transition from one equilibrium state to another via rapid snap-through can store elastic
energy and release it as kinetic energy for rapid motion as seen in Venus flytrap and …

A one-dimensional model for elastic ribbons: a little stretching makes a big difference
B Audoly, S Neukirch - Journal of the Mechanics and Physics of Solids, 2021 - Elsevier
Starting from the theory of elastic plates, we derive a non-linear one-dimensional model for
elastic ribbons with thickness t, width a and length ℓ, assuming t≪ a≪ ℓ. It takes the form of …

Curved crease origami and topological singularities enable hyperextensibility of L. olor
Fundamental limits of cellular deformations, such as hyperextension of a living cell, remain
poorly understood. Here, we describe how the single-celled protist Lacrymaria olor, a 40 …

Transient amplification of broken symmetry in elastic snap-through
A snap-through bifurcation occurs when a bistable structure loses one of its stable states
and moves rapidly to the remaining state. For example, a buckled arch with symmetrically …
