自从碳纳米管发现以来,其优异力学性质(小尺寸、低密度、高强度和高韧性)引起了人们的广泛关注,研究者们针对起各种力学行为进行了实验和理论上的大量研究。本文对碳纳米管力学性质的理论研究进行了回顾。首先简要的介绍了一下各种用于碳纳米管力学性质研究的理论方法,包括原子学方法和连续介质方法;然后对各种理论研究结果作了详细的综述,主要关注的是碳纳米管的扬氏模量、结构的影响、强度及塑性性质。本文对今后理论研究的方向作了初步展望。
Since the discovery of carbon nanotubes, their excellent mechanical properties (small size, low density, high strength and high toughness) have attracted people’s attention. Researchers have conducted many experimental and theoretical studies on various mechanical behaviors. In this paper, the theoretical study on the mechanical properties of carbon nanotubes is reviewed. First of all, a brief introduction to various theoretical methods for the study of mechanical properties of carbon nanotubes, including atomic methods and continuum methods; and then a comprehensive review of the results of various theoretical studies, the main concern is the carbon nanotubes Young’s modulus, effect of structure, strength and plasticity. This article made a preliminary forecast of the direction of theoretical research in the future.
