Abstract
Origami-inspired structures have been recently employed to solve several engineering problems and tubular origami structures have been of particular interest. These structures have remarkable strength-to-weight ratio, multistability and enhanced energy absorption. This paper presents a novel folding pattern, named waterpeace, for tubular origami inspired by a combination of the waterbomb and Yoshimura patterns. A bar-hinge model is adopted and the non-rigid characteristic and multistability is attested through a finite element analysis. A comparison with the well-known Kresling pattern is provided. Potential applications as robotic arms and energy absorbers are highlighted.
