摘要
负泊松比超材料,又被称为“拉胀”超材料,是一种力学超材料,具有特殊的力学性能,即在竖向受到压力(拉力)作用下,结构会发生横向收缩(膨胀)。这种特性与结构的拓扑排列关系密切,因此负泊松比超材料在多个领域具有广泛的应用前景。将对功能性负泊松比超材料的研究进展进行阐述,首先介绍了负泊松比超材料静力学性能方面的最新研究成果,包括常规的刚度提升、泊松比可调,和非常规的变形机制,以及使用机器学习定制结构性能;其次,分析了其抗冲击、抗爆炸、振动控制以及其他功能性应用的最新进展;最后,指出了当前功能性负泊松比超材料研究仍存在一些难题,并对未来的研究提供了若干参考性建议。
Negative Poisson s ratio metamaterials,also known as"auxetic"metamaterials,are a type of mechanical metamaterial that exhibits special mechanical properties.When subjected to vertical pressure(tension),the structure undergoes lateral contraction(expansion).This characteristic is closely related to the topological arrangement of the structure,making auxetic metamaterials have broad application prospects in many fields.This article will discuss the progress in the research of functional auxetic metamaterials.First,this paper introduces the latest research findings in the static properties of auxetic metamaterials,including conventional stiffness enhancement,tunable Poisson s ratio,and unconventional deformation mechanisms,as well as the use of machine learning to customize structural performance.Then,it analyzes the latest achievements in shock/explosion resistance,vibration control,and other functional applications.Last,it discusses some problems in the current research on functional auxetic metamaterials.This paper provides some suggestions for future related research.
