由于其优异的光学、弹性和电学性质，手性纳米线在纳米机电系统的传感器、探针和构建块等方面有着广泛的应用。本文提出了一种考虑表面效应和材料手性的手性纳米线的Euler-Bernoulli梁模型。将改进后的模型用于研究手性纳米线的弯曲和屈曲。研究发现，表面效应和材料手性对手性纳米线的弹性行为有显著影响。这一研究不仅有助于理解手性纳米线的尺寸依赖行为，而且有助于表征其力学性能。
Due to their superior optical, elastic and electrical properties, chiral nanowires have many applications as sensors, probes, and building blocks of nanoelectromechanical systems. In this paper, we develop a refined Euler–Bernoulli beam model for chiral nanowires with surface effects and material chirality incorporated. This refined model is employed to investigate the bending and buckling of chiral nanowires. It is found that surface effects and material chirality significantly affect the elastic behaviour of chiral nanowires. This study is helpful not only for understanding the size-dependent behaviour of chiral nanowires, but also for characterizing their mechanical properties.
