Abstract

Origami is widely used for honeycombs to improve mechanical behavior. This research presents an origami-honeycomb material based on the assembly of Miura patterns. Firstly, the geometry stacking scheme and rigid folding mechanism are discussed. Secondly, the in-plane compression behavior of the proposed origami-honeycomb is experimentally and numerically investigated. Its performance is then compared with a hexagonal honeycomb. Both results show that the origami-honeycomb outperforms the conventional honeycomb in terms of in-plane compression strength and energy absorption behavior. Subsequently, deformation mode and energy efficiency ratio are obtained to illustrate the mechanical behavior. A parametric analysis is also conducted by employing finite element simulations. Finally, the analytical model of the proposed origami honeycomb is built to estimate the gather strain and plateau stress.
