Abstract

In a 2D negative Poisson’s ratio (NPR) material, stretching (or compressing) in one direction results in expansion (or contraction) in the perpendicular direction, which limits its range of applications. Based on the 2D double re-entrant honeycomb (DRH) structure, this paper proposes three 3D DRH structures and derives the mechanical properties of these NPR structures. These 3D honeycomb structures are then fabricated using 3D printing technology, and their deformation behavior under uniaxial quasi-static loading is systematically investigated through experimental and simulation methods. By combining finite element analysis, experimental tests, and theoretical derivation, this study discusses the mechanical properties of the specimens, such as Poisson’s ratio behavior in detail. Furthermore, the energy absorption capacities of several 3D structures under quasi-static loading are compared. The results show that the finite element simulations, theoretical predictions, and experimental findings are in good agreement, and the 3D DRH structure exhibits a more stable concave mechanism, a higher energy absorption range, and better specific energy absorption compared to the 2D DRH structure.

一种新型三维双重入式增氧超材料的准静态破碎响应分析

在二维负泊松比（NPR）材料中，单向拉伸（或压缩）会导致垂直方向的膨胀（或收缩），这限制了其应用范围。基于二维双重入蜂窝结构，提出了三种三维双重入蜂窝结构，并推导了这三种结构的力学性能。利用3D打印技术制备了三维蜂窝结构，并通过实验和仿真方法系统研究了其在单轴准静态载荷作用下的变形行为。通过有限元分析、试验测试和理论推导相结合的方法，对试件的泊松比行为等力学性能进行了详细探讨。此外，还比较了几种三维结构在准静态载荷作用下的吸能能力。结果表明，有限元模拟、理论预测和实验结果吻合较好，与二维DRH结构相比，三维DRH结构具有更稳定的凹形机制、更高的能量吸收范围和更好的比能吸收。
