摘要

拉胀材料因其在变形下的新颖行为以及许多其他的材料特性（如抗断裂性、抗剪切性和能量吸收）而受到关注。将超弹性材料与拉胀结构相结合，它们的高度可变形的能力使设计具有增强力学可调性的结构成为可能。为此，提出了一种具有增强力学可调性的3D打印拉胀结构的设计方法。通过试验和数值分析，研究了所设计结构的面内压缩行为。结果表明，与传统的拉胀结构相比，具有拉胀结构的复合材料表现出了更高的刚度和增强的能量吸收性能。通过进一步调整正弦韧带的分布和振幅，生成了具有可调能量吸收、泊松比和变形模式的拉胀结构。展示了一种用于提高轻质结构的力学性能和能量吸收的设计方法。

Abstract

Auxetic materials have garnered attention due to their novel behavior under deformation and numerous other material properties

such as fracture resistance

shear resistance

and energy absorption. By integrating hyperelastic materials with auxetic structures

the highly deformable capability enables the design of structures with enhanced mechanical tunability. To this end

a design methodology for 3D printed auxetic structures with improved mechanical adjustability was proposed. The in-plane compressive behavior of the designed structures was investigated through test and numerical analyses. The results demonstrate that

compared to conventional auxetic structures

the composite material with auxetics structures exhibits higher stiffness and enhanced energy absorption performance. By further adjusting the distribution and amplitude of sinusoidal ligaments

auxetic structures with tunable energy absorption

Poisson ratio

and deformation modes were generated. This study presents a design approach for improving the mechanical properties and energy absorption of lightweight structures.
