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…
Nucleation of transition waves via collisions of elastic vector solitons
Hiromi Yasuda, Hang Shu, Weijian Jiao +2
In this work, we show that collisions of one type of nonlinear wave can lead to generation of a different kind of nonlinear wave. Specifically, we demonstrate the formation of topo…
Phase transitions in 2D multistable mechanical metamaterials via collisions of soliton-like pulses
Weijian Jiao, Hang Shu, Vincent Tournat +2
In this work, we report observations of phase transitions in 2D multistable mechanical metamaterials that are initiated by collisions of soliton-like pulses in the metamaterial. An…
Graph-theoretic estimation of reconfigurability in origami-based metamaterials
Koshiro Yamaguchi, Hiromi Yasuda, Kosei Tsujikawa +2
Origami-based mechanical metamaterials have recently received significant scientific interest due to their versatile and reconfigurable architectures. However, it is often challeng…
Wave manipulation using a bistable chain with reversible impurities
Hiromi Yasuda, Efstathios G. Charalampidis, Prashant K. Purohit +2
We systematically study linear and nonlinear wave propagation in a chain composed of piecewise-linear bistable springs. Such bistable systems are ideal testbeds for supporting nonl…
Leaf-like Origami with Bistability for Self-Adaptive Grasping Motions
