Tunable Pathway Selection in Coupled Multistable Snap-Through Systems
Weicheng Huang, Ke Huang, Jiaying Zhang +1
Multistable mechanical systems can store and release elastic energy through snap-through instabilities, but controlling transition pathways between stable states remains challengin…
Bifurcation reordering programs snap-through symmetry in folded elastic ribbons
Weicheng Huang, Qun Zhang, Bohan Zhang +1
Snap-through in slender elastic structures is often viewed as a sudden transition between stable configurations, yet the pathway taken during this transition can differ fundamental…
Dimple-Encoded Reprogrammable Origami
Qun Zhang, Weicheng Huang, Amir Hajiyavand +4
Programmable folding of elastic sheets typically relies on predefined flexible creases or active materials-enabled hinges, which lack intrinsic bistability and limit reprogrammabil…

Magnetic soft continuum robots (MSCRs) have emerged as a promising technology for minimally invasive interventions, offering enhanced dexterity and remote-controlled navigation in…
How do imperfections cause asymmetry in elastic snap-through?
Andrea Giudici, Weicheng Huang, Qiong Wang +4
A symmetrically-buckled arch whose boundaries are clamped at an angle has two stable equilibria: an inverted and a natural state. When the distance between the clamps is increased…
Localized tension-induced giant folding in unstructured elastic sheets
Kexin Guo, Marc Suñé, Kwok Ming Li +3
Buckling in compression is the archetype of elastic instability: when compressed along its longest dimension, a thin structure such as a playing card will buckle out-of-plane accom…
