“…The first type exhibits a force-displacement with the N-type, as depicted in figure 2(a). The second type, such as the bio-inspired polygonal multi-cell tube in compression [7], features a relatively flat force-displacement curve and achieves energy absorption primarily through unrecoverable plastic large deformation. However, for multistable metamaterials created through the buckling principle, plastic deformation is not desirable.…”

“…Energy-absorbing materials and structures find widespread usage in safeguarding humans and objects from impacts or collisions, including applications such as car bumpers, bullet-proof glass, helmets, and delicate goods packaging. Extensive research has been conducted to explore various methods of energy absorption for the creation of effective energy absorption materials and structures [6][7][8][9]. Previous studies primarily concentrated on plastic large deformation energy absorption of metal materials, particularly thin-walled structures, by introducing artificial defects like origami folding and corrugated tubes to control deformation modes [10][11][12][13].…”

Multistable metamaterials are artificially engineered materials that possess microarchitectures capable of maintaining multiple stable configurations. However, the realization of mechanical metamaterials with numerous programmable stable configurations using Double-Curved Beam (DCB) elements remains an ongoing challenge. In this study, we exploit the snapping-through buckling phenomenon exhibited by architected DCB structures to devise a mechanical metamaterial with a unique deformation mode, encompassing Multi-stability, Multi-path, Multi-platform, and Multi-step characteristics, hence referred to as a 4M mechanical metamaterial. By employing DCB as fundamental building block elements, architected metamaterials with two-dimensional (2D) series or parallel lattices are successfully constructed, as well as three-dimensional (3D) tubular geometries, denoted as DCB-n-m-C and DCB-n-m-M metamaterials, respectively. These metamaterials exhibit reversible energy absorption characteristics and the stiffness can be transformed from positive to negative under both small and large elastic deformations. Functional gradient design and tailored deformation capability are given by adjusting the wall thickness of each layer of double-curved beams, thereby demonstrating the multi-path deformation features inherent in 4M metamaterials. DCB-n-m-M metamaterials has multiple energy platforms in the process of snapping-through, which reflects the multi-platform characteristics of 4M metamaterial. Consequently, novel properties such as multistability, programmability, and reusable energy absorption characteristics are achieved. To comprehensively understand the mechanical response of the metamaterials, a thorough investigation into the influence of geometric parameters is conducted, including the number of polygonal edges, the number of the layers, and the aspect ratio Q. This investigation involves a combination of theoretical analyses, numerical simulations, and experimental verifications. The introduced design strategy paves a way for the innovative design of multistable, multi-step, tailored, and reversible deformation metamaterials.

“…Therefore, the research and optimization of the axial compression property of thin-walled metal tubes has always been the focus of the research in the field of structural impact resistance and energy absorption. [5][6][7] At present, the research on the improvement of mechanical properties and energy absorption efficiency of thin-walled metal tubes mainly focuses on the optimization of cross-sectional shape, axial size, and the addition of fillers. Porous materials such as foam aluminum have been used in the design of thin-walled tube filling because of their good light-weight energy absorption characteristics, which has important practical significance to improve its anti-compression property.…”

In this paper, a new type of thin-walled energy absorbing structure filled with auxetic lattice structure has been proposed. The deformation mode and mechanical responses of the new filled tube under compression load have been studied through quasi-static compression experiment and numerical simulation. A theoretical model for predicting the average compression force has been established and verified with simulation analysis. The influences of the geometrical parameters in the compression performance of the filled tube have been studied. The results show that the failure mode of the filled tube under compression load is local buckling failure. Compared with the single thin-walled tube and the lattice structure, the filled tube has better compression resistance. Through parameter analysis, it is clear that the anti-compression property of the filled tube can be significantly improved by increasing the wall thickness of the cell rod and the angle of the lower support rod, which will provide an important reference for the anti-impact optimization design of the negative Poisson’s ratio lattice filled structure.

Multicellular, thin‐walled impact tubes have been intensely studied and used in various engineering fields in recent years due to their lightweight, high performance, ease of application, superior energy absorption, and stable deformation characteristics. In this study, energy absorption, crashworthiness performances, and deformation properties of thin‐walled structures manufactured from polylactic acid (PLA+) and acrylonitrile butadiene styrene (ABS) using fused deposition modeling (FDM) technology were compared under quasi‐static axial compression. Thin‐walled structures consist of multicellular tubes connected by concentric corner‐edge connections with square and hexagonal cross‐sections. Experimental testing outcomes indicate that the energy absorption capacity increases with increasing the number of corners in multicellular structures. The tubes with square wall‐to‐wall (S‐WW) and hexagonal wall‐to‐wall (H‐WW) cross‐sections exhibit superior crashworthiness performance compared to other cross‐sections. Based on the experimental results, the absorbed energy by WW patterned PLA+ square tubes are 19%, 7%, and 46% more than that of wall‐to‐corner (WC), corner‐to‐wall (CW), and corner‐to‐corner (CC) patterned tubes, respectively, while it is 11%, 19%, and 80% more in hexagonal cross‐section tubes, respectively. This study provides an informative reference for easier applicability of multicellular energy‐absorbing structures with 3D‐print and the design of corner‐edge connections of internal connections in multicellular structures.
