摘要 系统地研究了金属-碳纳米管复合结构的力学行为,考察了单轴压缩载荷作用下填充管的临界屈曲应变对管内金属原子数目的依赖性,分析了管的几何特征,包括管径、管长及手性,对填充管变形与力学行为的影响,并与连续体力学模型的预测进+行了对比分析。本文的研究结果对金属-碳管复合结构的理论研究和工程应用都具有较好的指导意义。 A detailed study is carried out on the mechanical behaviour of metal-filled single-walled carbon nanotubes under uni-aixal compression. Influence of several factors, including the number of encapsulated metal atoms, tube radius, tube length and tube chirality, is examined and compared with those predictions obtained from continuum mechanics. Results in this work provide a good reference for both theoretical study and industrial application of metal-carbon nanotube structures.
