Lattice structures have the potential for application in tensile conditions. However, limited studies addressed behaviours of such and compared them with their compressive behaviours. In this paper, re-entrant structure as foundation was selected to develop new 3D hybrid auxetic honeycomb lattice structures, each characterized by a unique unit cell configuration that features interconnected centre honeycomb, differentiating it from 2D structures. A series uniaxial quasi-static tests, followed simulations were conducted on these investigate compare energy absorption characteristics. The results show there significant differences between terms mechanical under tension compression. Especially, smallest value load 86% higher than largest load. stiffnesses loading about 84–122 times those identical corresponding when they compressed. Meanwhile, progressive stretching, buckling collapse mechanisms observed exhibited excellent absorptions traditional basic structure. outer frame had direct influence Poisson's ratio. work indicates stiffness can be enhanced embedding umbrella shaped elements.

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.
