基于EAM镶嵌原子势函数 ,采用分子动力学模拟了零温下纳米多晶铜的微观结构 .首先用Voronoi几何方法构造了 5个纳米多晶铜数值模型 ,在 30 0K弛豫 5 0ps并退火至 0K .然后分析零温下弛豫模型的径向分布函数、原子能量、配位数、原子Voronoi体积、以及本征应力分布 Based on the EAM inlaid atomic potential function, the microstructure of nano-polycrystalline copper at zero temperature was simulated by molecular dynamics method. First, five nano-polycrystalline copper numerical models were constructed by Voronoi geometry method, 0K. Then the radial distribution function, atomic energy, coordination number, atomic Voronoi volume, and intrinsic stress distribution
