| 摘 要： | 纳米尺度下结构力学行为因为表面效应和尺寸效应而与宏观尺度下结构力学行为有着本质的不同，分子动力学方法因其能通过原子运动理解结构变形细节而在纳米结构力学行为模型中得到广泛应用，本文综述了近期在纳米丝结构力学研究方面的进展，包括自由弛豫态，应力应变关系，表面效应和尺寸效应，应变率效应等。

| Abstract: | Mechanical behavior of the materials with nanoscale is essentially different from that at macroscale, resulting from surface effect and size effect. Molecular dynamics method can elucidate the structure deformation in detail with atomic motion, so it is widly used to simulate the structures of material with nanoscale. The progress in mechanical behavior of metal nanowires was reviewed, including free relaxation state. Stress-strain relation, surface efect, size effect and strain rate effect. |
