Hexagonal perforated honeycomb (HPH) metamaterials were designed, fabricated and investigated in this work. Initially, the mechanical properties deformation modes of various proposed HPH (HPH-U, HPH-1L HPH-3L) under quasi-static vertical compression analyzed using experimental finite element methods. The findings reveal significant improvements energy absorption due to hierarchical expandable design. Notably, auxetic effect is diminished. Subsequently, impact key dimensional parameters on Poisson's ratio behavior was explored. results highlighted that an increase elliptical perforation major axis minor enhanced but compromised load-bearing absorptive capacity. Additionally, displayed exceptional performance horizontal compression, with their structure enabling them withstand both impacts while exhibiting excellent capabilities. study also identified relative density as a crucial factor influencing performance. Finally, subjected multiple repetitive compressions, meticulously analyzing variations diverse ratios. Due distinctive structural design impressive properties, demonstrate immense potential for applications automotive engineering sports protection fields.

Abstract Auxetic metamaterials refer to materials and structures with extraordinary deformation, i.e., transverse expansion (contraction) under uniaxial tension (compression). In recent decades, a very wide range of innovative functional performance has been discovered stemming from this behavior. This desirable exhibition adaptivity, programmability, functionality provides great potential in soft intelligent systems. However, thus far, the mainstream research on auxetic focused subjective design, monotonic mechanical properties, passive tunability. review thorough overview classical properties applications, primary objective proposing new roadmap auxetics for advances interdisciplinary field. The fundamental works are categorized different configurations mechanisms. particular, integration shape morphing, actuation, sensing, multiphysical response, inverse design is reviewed detail. To accelerate development smart structural systems, applications generalized into robotics (outside body), human–machine interaction (surrounding healthcare devices (inside body). Finally, several significant topics emphasized theory, material choice, manufacturing technique, applications.

The present study aims at developing reusable metamaterials fabricated by 4D printing technology. Honeycomb were manufactured via fused deposition modeling (FDM) with shape memory polymers (SMPs). reusability of these was determined through cyclic cold programming experiments, where each cycle involved a loading-unloading-heating (shape recovery)-cooling process. novelty this paper lies not only in experimentally demonstrating the recoverability reversing plastic deformation based on effect SMPs, but also studying their SMP under and materials unit-cell types mechanical degradation. results reveal that, one single compression cycle, polylactic acid (PLA) hexagonal honeycomb dissipated 22% more energy than polyethylene terephthalate glycol (PETG) counterpart because higher elastic modulus PLA leads to larger critical buckling load for segments structures. Furthermore, PETG re-entrant 25% due its negative Poisson's ratio overall uniform pattern. More importantly, it is found that multiple cycles, maintained an dissipation capacity 78.3% Cycle 6, nearly 3.5 times as result better ductility PETG. Moreover, could be reused 17 while 12 cycles. This unit cells are failure-resistant less concentration deformation. demonstrate constituent unit-cells failure resistance can reduce degradation, thereby exhibiting metamaterials.
