在发现碳纳米管后不久,对于这些有趣结构的力学性质——包括高强度、高硬度、低密度和结构的完美性的理论预测,使人们认识到它们可能具有理想的科技应用价值.对这些预测的实验验证或个别验伪以及大量基于不同模型的计算机模拟方法,使得逾10年来对碳纳米管力学的理解日趋深入但远未达到尽头.本文回顾了理论预测,并对这种微小结构的观察和操作中经常用到的富有挑战性的实验技术进行了讨论.略述了采用的计算方法包括从头算法量子力学模拟、经典分子动力学和连续介质模型.多尺度和多物理模型的发展和模拟工具自然而然作为连接基础科学问题和工程应用的结果而出现,而这个主题仍然正在抓紧研究中.这里介绍了研究此主题的一些方法.注意力主要集中于研究力学性质的揭示方面,如杨氏模量、弯曲刚度、屈曲准则、拉伸和压缩强度.最后,讨论了利用这些性质的几个令人兴奋的应用例子,包括纳米绳束、填充的纳米管、纳米机电系统、纳米传感器和纳米管增强复合材料,引用了349篇参考文献。
Shortly after the discovery of carbon nanotubes, theoretical predictions of the mechanical properties of these interesting structures, including high strength, high hardness, low density and structural perfection, have led to the recognition that they may have ideal scientific and technological applications. Predictive experimental verification or individual verification and a large number of computer simulation methods based on different models have made the understanding of carbon nanotube mechanics more and more ten years far from the end but far from the end.This paper reviews the theoretical prediction and analyzes the microstructure The most challenging experimental techniques commonly used in observation and manipulation are discussed, and the computational methods outlined include ab initio quantum mechanics simulations, classical molecular dynamics and continuum models. The development of multiscale and multiphysics models and Simulation tools are naturally emerging as a result of linking basic science and engineering applications, and the subject is still being worked through. Here are some of the ways in which this topic can be explored: Attention has focused on the discovery of mechanistic properties such as Young’s Modulus, Bending Stiffness, Buckling Criterion, Tensile and Compressive Strength. Finally, the discussion A few exciting examples of applications that take advantage of these properties include nanowire bundles, filled nanotubes, nanoelectromechanical systems, nanosensors and nanotube-reinforced composites, citing 349 references.
