The principles of cascading power limits in small, fast biological and engineered systems

M Ilton, MS Bhamla, X Ma, SM Cox, LL Fitchett, Y Kim… - Science, 2018 - science.org
INTRODUCTION Mechanical power, whether for launched missiles or running humans, is
limited by the universal, physical trade-off between force and velocity. However, many …

A new wrinkle on liquid sheets: Turning the mechanism of viscous bubble collapse upside down

AT Oratis, JWM Bush, HA Stone, JC Bird - Science, 2020 - science.org
Viscous bubbles are prevalent in both natural and industrial settings. Their rupture and
collapse may be accompanied by features typically associated with elastic sheets, including …

Fragmentation versus cohesion

E Villermaux - Journal of Fluid Mechanics, 2020 - cambridge.org
Capillarity is the familiar manifestation of the cohesion of liquids. Since Laplace (Traité de
mécanique céleste, vol. IV, supplément au livre X: Sur l'action capillaire, 1805, pp. 1–65), we …

Elastic Wave Packets Crossing a Space-Time Interface

A Delory, C Prada, M Lanoy, A Eddi, M Fink… - Physical Review Letters, 2024 - APS
The interaction between waves and evolving media challenges traditional conservation
laws. We experimentally investigate the behavior of elastic wave packets crossing a moving …

Geometry and fragmentation of soft brittle impacted bodies

N Vandenberghe, E Villermaux - Soft Matter, 2013 - pubs.rsc.org
Some mechanisms of shape selection and fragmentation patterns of impacted or strongly
solicited elastic bodies of simple geometry are reviewed. By strongly solicited we mean …

Dynamics of wrinkling in ultrathin elastic sheets

F Box, D O'Kiely, O Kodio, M Inizan… - Proceedings of the …, 2019 - pnas.org
The wrinkling of thin elastic objects provides a means of generating regular patterning at
small scales in applications ranging from photovoltaics to microfluidic devices. Static wrinkle …

Dynamic buckling of an elastic ring in a soap film

F Box, O Kodio, D O'Kiely, V Cantelli, A Goriely… - Physical Review Letters, 2020 - APS
Dynamic buckling may occur when a load is rapidly applied to, or removed from, an elastic
object at rest. In contrast to its static counterpart, dynamic buckling offers a wide range of …

Dynamic recoil in metamaterials with nonlinear interactions

X Liang, AJ Crosby - Journal of the Mechanics and Physics of Solids, 2022 - Elsevier
Biological systems can generate motions with high acceleration and velocity via dynamic
recoil. Traditionally, recoil dynamics in unstructured linear elastic systems are based on …
