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.

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.
