论文摘要
在介绍的工作中，考虑了各种尺寸的碳纳米颗粒（纳米原子和富勒烯）的机械刚度的特征。用平均键刚度$ k_0 $的术语来研究并解释了纳米座型刚度（与散装钻石相比）的增强。结果表明，$ k_0 $在描述各种碳纳米结构的描述中很有用，并可靠地估计其不可压缩性。此外，我们发现只能基于放松的原子几何形状来很好地估计$ k_0 $。
In the presented work, the features of mechanical stiffness of carbon nanoparticles (nanodiamonds and fullerenes) in a wide range of sizes are considered. The enhancement of nanodiamonds stiffness (comparing to bulk diamond) is studied and explained in the terms of average bond stiffness $k_0$. It is shown that $k_0$ can be useful in the description of various carbon nanostructures and gives reliable estimates of their incompressibility. Moreover, we found that $k_0$ can be well estimated based only on relaxed atomic geometry.
