The Collective Snapping of a Pair of Bumping Buckled Beams
Lennard J. Kwakernaak, Arman Guerra, Douglas P. Holmes +1
When a pair of parallel buckling beams of unequal width make lateral contact under increasing compression, eventually either the thin or the thick beam will snap, leading to collec…
Germain Curvature: The Case for Naming the Mean Curvature of a Surface after Sophie Germain
Douglas P. Holmes
How do we characterize the shape of a surface? It is now well understood that the shape of a surface is determined by measuring how curved it is at each point. From these measureme…
Self-Ordering of Buckling, Bending, Bumping Beams
Arman Guerra, Anja Slim, Douglas P. Holmes +1
A collection of thin structures buckle, bend, and bump into each-other when confined. This contact can lead to the formation of patterns: hair will self-organize in curls; DNA stra…
Wrinkling and developable cones in centrally confined sheets
Lucia Stein-Montalvo, Arman Guerra, Kanani Almeida +2
Thin sheets respond to confinement by smoothly wrinkling, or by focusing stress into small, sharp regions. From engineering to biology, geology, textiles, and art, thin sheets are…
Emergence of Structure in Columns of Grains and Elastic Loops
Arman Guerra, Douglas P. Holmes
It is possible to build free-standing, load-bearing structures using only rocks and loops of elastic material. We investigate how these structures emerge, and find that the necessa…
Efficient snap-through of spherical caps by applying a localized curvature stimulus
Lucia Stein-Montalvo, Jeong-Ho Lee, Yi Yang +3
In bistable actuators and other engineered devices, a homogeneous stimulus (e.g. mechanical, chemical, thermal, or magnetic) is often applied to an entire shell to initiate a snap-…
