Supratransmission in Lattices with Purely Nonlinear Coupling
Defri Ahmad, Tae-Yeon Kim, Andreas Schiffer +2
Supratransmission is examined in nonlinear lattices with purely nonlinear coupling, extending the phenomenon to systems that lack a linear pass band. In contrast to standard lattic…
Inverse design of flat-foldable volumetric origami with smooth curved profile
Byoung-Gyu Kim, Geonhee Cho, Yasuhiro Miyazawa +2
Through flat-folding, origami provides an extremely compact packaging strategy for deployable structures in aerospace, architecture, and robotics. However, origami's flat, volumele…
Size-Dependent Properties of Miura-ori Tessellations
Chaewon Baek, Tomohiro Tachi, Jinkyu Yang +1
We investigate the size-dependent behavior of Miura-ori-based origami tessellations by changing the number of origami unit cells. For large tessellations, the Miura-ori sheet gener…
A Unified Framework for Kinematic Simulation of Rigid Foldable Structures
Dongwook Kwak, Geonhee Cho, Jiook Chung +1
Origami-inspired structures with rigid panels now span thick, kirigami, and multi-sheet realizations, making unified kinematic analysis essential. Yet a general method that consoli…
Physics-Informed Neural Networks for Programmable Origami Metamaterials with Controlled Deployment
Sukheon Kang, Youngkwon Kim, Jinkyu Yang +1
Origami-inspired structures provide unprecedented opportunities for creating lightweight, deployable systems with programmable mechanical responses. However, their design remains c…
Topological edge states and amplitude-dependent delocalization in quasiperiodic elliptically geared lattices
Shuaifeng Li, Di Zhou, Feng Li +2
We present a class of mechanical lattices based on elliptical gears with quasiperiodic modulation and geometric nonlinearity, capable of exhibiting topologically protected modes an…
