Beyond Snap-Fit: Optimizing the Lifting Capabilities of a Partial Cylindrical Shell
Grace K. Curtis, Ian M. Griffiths, Dominic Vella
The cylindrical snap-fit is a ubiquitous fastening method that is both simple to manufacture and assemble, and yet secure. It consists of a partial cylindrical shell that `snaps' o…
Shape matters: Body dynamics underlies efficient jumping
Marc Suñé, Lucas Selva, Cristóbal Arratia +2
Many small animals, particularly insects, use power-amplification to generate rapid motions, such as jumping, that would otherwise be impossible given the standard power density of…
Inverse design of a magneto-elastica for shape-morphing
JiaHao Li, Yingchao Zhang, Weicheng Huang +4
Slender magnetic elements provide a versatile platform for programmable shape-morphing under remote magnetic actuation. However, a general and physically interpretable framework fo…
Universal wrinkling dynamics of a sheet on viscous liquid
Ayrton Draux, Marco Rizzo, Dominic Vella +3
We investigate the wrinkling dynamics of a thin elastic sheet that is indented or compressed while floating on a viscous liquid. We show that the deformation speed controls the dyn…
Bridging a gap: A heavy elastica between point supports
Grace K. Curtis, Ian M. Griffiths, Dominic Vella
We study the deformation and slip-through of a heavy elastic beam suspended above two point supports and subject to an increasing body force -- an idealized model of a fibre trappe…
Mechanical Reinforcement of Graphene via Wrinkling
Hadi Arjmandi-Tash, Roshan Prasad, Hanqing Liu +3
Mechanical cantilevers are central to nanotechnology, with ultimate sensitivity achieved at the atomic limit, where low bending rigidity makes stability the fundamental challenge.…
