Abstract

Reconfigurability and tunability of the tessellation of Tachi-Miura Polyhedron (TMP), an origami-based cellular structure composed of bellows-like unit cells after its fabrication was investigated. By combining origami-based tessellation design, analytical method with rigid-origami modeling, efficient manufacturing of a prototype, and experimental verification, our research results show that a significant range of in-situ tunability in effective density, Young's modulus, and Poisson's ratio can be obtained within the elastic regime with orders of magnitude changes.
