摘要
在团簇多重标号技术基础上,提出了团簇探测的新算法,并以此作为大尺度二维和三维分子动力学模拟冲击加载金属材料微喷射粒子团簇分析的子程序.以二维为例描述了算法的逻辑结构,测试分析了算法的运行效率,并将其应用到二维分子动力学模拟冲击加载金属Cu和Al微喷射粒子的团簇统计分析中,对微喷射粒子团簇尺寸分布得到一些规律性认识.
Based on the cluster multiple labeling technique, a novel cluster detection algorithm is presented as an analysis subroutine in two- and three-dimensional molecular dynamic simulations of ejecta that take place as a planar shock wave encounters a free metal surface. The algorithm is described, tested, and used to detect cluster distribution of ejecta from copper and aluminum under a shock loading. The information obtained about the size, distribution, evolution of the cluster is helpful in the understanding of ejection.
