2D-to-3D transformation of ring origami via snap-folding instabilities
Lu Lu, Sophie Leanza, Luyuan Ning +1
Ring origami, consisting of closed-loop rods, is a class of shape-morphing structures that undergo shape transformation through folding enabled by snap-buckling instabilities, refe…
Elastic Rod Origami (RodOri) for Programming Static and Dynamic Mechanical Properties
Sophie Leanza, Jeseung Lee, Ruike Renee Zhao
Reconfigurable mechanical systems enable precise programmable control over structural properties, opening new opportunities in architected materials, adaptive devices, and multifun…
Multiple equilibrium states of a curved-sided hexagram: Part II-Transitions between states
Lu Lu, Jize Dai, Sophie Leanza +2
Curved-sided hexagrams with multiple equilibrium states have great potential in engineering applications such as foldable architectures, deployable aerospace structures, and shape-…
Multiple equilibrium states of a curved-sided hexagram: Part I-Stability of states
Lu Lu, Jize Dai, Sophie Leanza +2
The stability of the multiple equilibrium states of a hexagram ring with six curved sides is investigated. Each of the six segments is a rod having the same length and uniform natu…
