In this study, we analyse the kinematics and elastic properties of multiple assembled origami morphologies on the basis of various origami folding techniques. By modifying Miura-ori pattern, mechanical metamaterials such as curved origami shell and large-scale bendable elastic structures are developed. The concept of in-plane Poisson’s ratio is extended to the curved shell structures and the existence of a critical folding state is presented by analysing the geometric characteristics. An analytical model is adopted to study the mechanical properties of the assembled structures and elastic behaviors such as load softening and snap-through are obtained. By introducing origami assemblages, we extend the design space of mechanical metamaterials and provide benchmarks for their practical applications in science and engineering.
