使用经验模型计算单层和多层纳米管的弹性性能。据预测，纳米管是最强的材料。杨氏模量和剪切模量与金刚石相当，但体积模量几乎是金刚石的两倍。研究表明，弹性模量对纳米管结构的细节（例如螺旋度、管半径和层数）不敏感。这些不寻常的特性确保纳米管将具有广泛的潜在应用。 (C) 1997 爱思唯尔科学有限公司。
Elastic properties of single-and multilayered nanotubes are calculated using an empirical model. It is predicted that the nanotubes are the strongest materials. The Young's modulus and the shear modulus are comparable to that of the diamond, but the bulk modulus is almost twice as large. Elastic moduli are shown to be insensitive to details of nanotube structure such as helicity, tube radius and number of layers. These unusual properties ensure that nanotubes will have a wide range of potential applications. (C) 1997 Elsevier Science Ltd.
