Article
Reusability and multi-functionality are challenges in the design of energy-absorbing structures, which may realize through special metamaterials. Multistable mechanical metamaterials with different energy barriers are one of the most promising candidates to achieve this goal. Here, a novel snap-fit based modular multistable mechanical metamaterial...
Article
Multi-cell tubes can be flexibly designed to exhibit excellent energy absorption capacity and lightweight property via the topological configuration design of their cross-section characteristics such as hierarchy and gradients. In this paper, we focus on the design of multi-cell structure, which combined with topological configuration design and sp...
Article
In this paper, we focus on the design of multi-cell hexagonal tubes filled with self-similar inspired multi-cell tubes with a different layout. The effect of the hierarchy design, layout optimization and the number of self-similar inspired substructures were numerically investigated. The multi-criteria decision-making method (COPRAS) is used to eva...

In this paper, we presented an extended family of Miura-ori structures with programmable multi-step deformation via arraying and mirroring. We found that there is a competitive relationship between thickness gradient and structural gradient for these origami structures. Furthermore, we demonstrate that the multi-step deformation can be designed by...

Self-similar multi-cell structures have been widely applied in engineering fields for their excellent mechanical properties and multi-functional characteristics. In this paper, self-similar inspired multi-cell tubes are constructed by replacing the substructures according to different strategies. The hybrid tubes are built by the space-filling and...

The unique mechanical behavior of polyline crease (PLC) origami structures inspired by the Tachi-Miura polyhedron (TMP) is investigated. We explore the potential usage as mechanical metamaterials that exhibit negative Poisson’s ratio, self-locking mechanism, and load capacity simultaneously. Poisson’s ratio, locked folding ratio, dimensionless forc...

Origami structures, whose mechanical properties can be tuned by programing the crease network, have been sought in application including DNA origami nanorobots and deployable space structures. However, the existing researches mainly placed on the cylindrical origami tubes or the periodic cellular metamaterials, which are based on the stacking of in...
