Summary:
We study unique wave propagation in origami-based mechanical metamterials composed of foldable origami structures, specifically Triangulated Cylindrical Origami (TCO). By using the simplified TCO unit cell as a building block, we design and analyze the TCO-based mechanical metamaterials in which multiple unit cells stacked vertically. Under compressive impact, the TCO-based system exhibits unique wave dynamics such as the formation of rarefaction waves. Also, if the system consists of two distinctive TCO unit cells stacked in an alternating way, we observe formation of frequency band structures. Based on these unique characteristics, the TCO-based mechanical metamaterials have great potential for engineering applications.
