| 中文摘要: |
| 分子动力学计算机模拟是研究复杂凝聚态系统的有力工具,但存在着时间尺度和空间尺度小的局限性.准分子动力学方法,有望成为研究凝聚态系统的跨尺度问题的有力工具.对径受压圆盘的算例表明,准分子动力学方法在解决大尺度力学问题时是有效的. |
| 英文摘要: |
| A new multi-scales quasi-molecular dynamics method is proposed. The method is based on molecular potential functions and time-space-scale corelation. A declining elastic wave propagation in a disc subjected to a pair opposite concentrate compressive loading symmetrically is simulated with the method. The method is a powerful tool to solve macro-scale dynamic problems and convenient to transform from micro-scales to macro-scales. |
