“…By cutting or perforating, the periodic holes are obtained in the plate structure to prepare the auxetic structures. For instance, Hu et al [30,40] made antitrichiral and re-entrant antichiral honeycomb samples from a piece of ABS plate by laser cutting technology. Carta [139] and Taylor et al [140] have perforated Lexan polycarbonate sheet and aluminum plate, respectively, to fabricate porous auxetic structures.…”

Auxetic mechanical metamaterials (AMMs), as an exciting paradigm of metamaterials, have attracted increasing attention due to their interesting mechanical properties (e.g. negative Poisson's ratio), as well as the emergence of advanced manufacturing technology (e.g. 3D printing). Although various reviews on AMMs, their structures, properties, and applications, have existed, it still lacks a comprehensive review in terms of manufacturing methods. Herein, the latest progress in AMMs is extensively reviewed, including AMMs' structures, characteristics, manufacturing methods, and applications. In addition, the current challenges and future works of AMMs are concluded and discussed. This Review aims to serve as a collection of knowledge that supplies more comprehensive understanding and inspiration to support further developments of AMMs from the perspective of design and manufacturing.

“…To achieve the axisymmetric auxetics, Yang and Ma (2020) proposed a systematic design strategy with rotationally symmetric transverse deformation mode. Furthermore, the relationships between the topology and specific mechanical or physical properties are systematically analyzed, indicating a great potential in a function-oriented view of design (Hu et al , 2018a; Mizzi et al , 2018; Mardling et al , 2020).…”

Purpose Auxetics metamaterials show high performance in their specific characteristics, while the absolute stiffness and strength are much weaker due to substantial porosity. This paper aims to propose a novel auxetic honeycomb structure manufactured using selective laser melting and study the enhanced mechanical performance when subjected to in-plane compression loading. Design/methodology/approach A novel composite structure was designed and fabricated on the basis of an arrowhead auxetic honeycomb and filled with polyurethane foam. The deformation mechanism and mechanical responses of the structure with different structural parameters were investigated experimentally and numerically. With the verified simulation models, the effects of parameters on compression strength and energy absorption characteristics were further discussed through parametric analysis. Findings A good agreement was achieved between the experimental and simulation results, showing an evidently enhanced compression strength and energy absorption capacity. The interaction between the auxetic honeycomb and foam reveals to exploit a reinforcement effect on the compression performance. The parametric analysis indicates that the composite with smaller included angel and higher foam density exhibits higher plateau stress and better specific energy absorption, while increasing strut thickness is undesirable for high energy absorption efficiency. Originality/value The results of this study served to demonstrate an enhanced mechanical performance for the foam filled auxetic honeycomb, which is expected to be exploited with applications in aerospace, automobile, civil engineering and protective devices. The findings of this study can provide numerical and experimental references for the design of structural parameters.

“…Existing studies [ 9 , 10 , 11 , 12 ] mostly focused on the relationship between structural geometries and mechanical properties. Both the quasi-static and dynamic mechanical behaviors have been extensively investigated for the lattice structures, including honeycombs [ 13 , 14 ], face-centered cubes (FCC) [ 15 , 16 ], and body-centered cubes (BCC) [ 17 ]. Although being lightweight, the porous characteristics of the lattice structures usually compromise their mechanical properties compared with their solid counterparts.…”

Our previous work reported a novel lattice structure composed of modified face-centered cubic (modified FCC) cells with crossing rods introduced at the center of each cell. In this work, the proposed modified FCC lattice is further investigated to ascertain its compression behaviors under different loading rates. For this purpose, numerical simulations were carried out for compressing the two-dimensional and three-dimensional modified FCC lattice structures with different loading rates, and to compare their deformation modes and energy absorption capacity under different loading rates. In addition, lattice specimens were fabricated using selective laser melting technology and quasi-static compression experiments were performed to validate the finite element simulations. The results indicate that the proposed modified FCC lattices exhibit better load-bearing capacity and energy absorption than the traditional FCC lattices under different loading rates. Under high-speed loading, the modified FCC structure is less susceptible to buckling, and the length ratio of the central cross-rod corresponding to maximum energy absorption capacity is larger.
