Abstract

We investigate a design method on tessellations of Tachi-Miura Polyhedron (TMP), origami-based auxetic mechanical metamaterials composed of bellows-like structures. In recent years, mechanical metamaterials have shown a significant amount of intriguing properties both statically and dynamically. In order to provide design tools for this class of metamaterials in a comparable way to the conventional materials, we utilize three-dimensional Ashby charts with Poisson’s ratio to visualize the mechanical properties. This three-dimensional Ashby chart emphasizes the advantage of origami metamaterials compared to conventional materials while maintaining the comparability of general mechanical properties. We analyze mechanical properties both analytically and experimentally. These methods can pave the way for the further utilization of advanced mechanical metamaterials.
