Applied Sciences, Journal Year: 2024, Volume and Issue: 14(3), P. 1028 - 1028

Published: Jan. 25, 2024

Based on the concept of component assembly, a novel star polygon-coupled honeycomb metamaterial, which achieves collaborative improvement in load-bearing capacity and vibration suppression performance, is proposed based common polygonal structure. The compression simulation experiment results show that metamaterial three times more than initial metamaterial. Additionally, metal pins are attached particle damping applied to regulate its bandgap properties; influence configuration parameters, including size, number, position, material pins, bandgaps also investigated. can be conveniently effectively regulated by adjusting parameters suppress vibrations corresponding frequency band. Particle used continuously adjust further enhance other bands. This paper provides reference for design optimization metamaterials.

A review of curved crease origami: design, analysis, and applications

Frontiers in Physics, Journal Year: 2024, Volume and Issue: 12

Published: July 1, 2024

Origami structures with morphing behaviours and unique mechanical properties are useful in aerospace deployable structures, soft robots metamaterials. Curved-crease origami, as one of the variants origami family, has a curve that connects two vertices crease compared to straight counterpart. This feature couples folding facet bending during process, providing versatile design space metamaterials tunable stiffness, multi-stability behaviours. However, current techniques mostly for simple geometries intuitive construction, modelling technique focuses on using conventional finite element method, intrinsically complex make specimens difficult manufacture, which further hinders development curved-crease structures. Thus, it is valuable review state-of-the-art origami. paper presents methodology, analytical methods, applications over years, discusses their strengths, identifies future challenges provides an outlook concept.
