Modular fabrication and design of thick rigid-foldable origami metamaterials
Sunao Tomita, Hiroki Kobayashi, Shoko Arita +4
Origami metamaterials offer significant potential for stiff deployable structures However, fabricating load-bearing cellular structures from thick panels introduces geometric inter…
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…
Multistable Curved-Crease Origami Blocks for Reconfigurable Modular Building System
Munkyun Lee, Joseph M. Gattas, Tomohiro Tachi
This study proposes a reconfigurable modular building system that assembles multistable curved-crease origami blocks. Curved-crease origami is designed with even-vertex polygonal t…
A Proper Definition of Higher Order Rigidity
Tomohiro Tachi
[Connelly and Servatius, 1994] shows the difficulty of properly defining n-th order rigidity and flexiblity of a bar-and-joint framework for higher order (n >= 3) through the intro…
Stiff deployable structures via coupling of thick Miura-ori tubes along creases
Sunao Tomita, Kento Shimanuki, Kazuhiko Umemoto +3
Origami-based structures play an important role in the realization of deployable mechanisms and unique mechanical properties via programmable deformation by folding. Among origami-…
