Abstract

Zero Poisson's ratio (ZPR) structures have attracted significant attention due to their remarkable dimensional stability, mechanical decoupling capability, and reduction of contact-induced effects, making them desirable in various engineering applications. However, most existing ZPR structures suffer from limited adaptability under large strains, which restricts their practical implementation. To address this challenge, this study proposes a novel ZPR design based on a mirror-stacked tetra-missing rib honeycomb (MSTMH) with monoclinic chirality. The mirror-stacked configuration effectively suppresses the Poisson's effect in the transverse direction, enabling a stable zero Poisson's ratio behavior over a wide strain range. To evaluate its performance, four MSTMH samples were fabricated using 3D printing, and uniaxial tensile tests were conducted. Finite element (FE) simulations and theoretical derivations were further employed to analyze key structural parameters, including the effective elastic modulus and ZPR strain range. The theoretical predictions show good agreement with both the experimental and numerical results. This work provides new insights and design strategies for achieving highly stable and large-deformation-tolerant ZPR metamaterials.
