Abstract

We investigate the extreme wave event in mechanical metamaterials composed of Triangulated Cylindrical Origami (TCO). Specifically, we focus on the realization of so-called rogue waves by employing a homogeneous one-dimensional chain constructed from the TCO unit cells. Our numerical simulation shows the significant energy focusing in the very limited number of unit cells. The wave localization behavior varies as a function of the geometrical parameters of the TCO, which enables us to manipulate the wave localization. The configurability of the wave localization using the TCO can be leveraged for energy harvesting purposes in engineering applications.
