The exceptional energy absorption, deformability, and tuneable Poisson's ratio properties of negative (NPR) honeycomb biomimetic structures make them highly suitable for applications in aerospace, medical, acoustic stealth industries. present study proposes a re-entrant hybrid (REHH) structure comprising octagonal unit cell hexagonal cell. Theoretical models the in-plane elastic modulus are established based on beam theory, these validated through finite element (FE) simulations tensile experiments conducted REHH samples. influence geometry parameters behaviours is investigated. results indicate that NPR performance exhibits superior deformation capability compared with four-point star (FSHH) structure. experimental samples exhibit significant displacement capabilities
