Roberto Arevalo, Iker Zuriguel, Diego Maza

摘要:

定义了不同粒系综的力网络,并利用复杂网络工具研究了其拓扑性质。特别地,对于在正方形盒中压缩的每组颗粒,引入了确定哪些接触符合网络的力阈值。因此,网络的拓扑特性作为该参数的函数进行了分析。由此获得的结构特征的表征,可能是有用的,在理解这类介质所表现出的宏观物理行为。

英文摘要:

The force networks of different granular ensembles are defined and their topological properties studied using the tools of complex networks. In particular, for each set of grains compressed in a square box, it is introduced a force threshold that determines which contacts conform the network. Hence, the topological characteristics of the network are analyzed as a function of this parameter. The characterization of the structural features thus obtained, may be useful in the understanding of the macroscopic physical behavior exhibited by this class of media.
