Research Progress on Simulation Modeling of Metal Foams

摘要:

对目前较为常用的6种泡沫金属的计算机仿真模型进行了概述和分析。这6种模型包括：立方胞模型，Gibson-Ashby模型，八面体模型，十四面体模型，Voronoi模型和三维随机球模型。不仅对每一种模型的结构进行了描述，而且对各种仿真模型在应用研究中存在的优缺点进行了综合分析。

Abstract:

The metal foams are a novel kind of structural and functional composite materials, which have attracted a wide attention due to their particular structure and characteristics. In order to promote the research and the application of metal foams, six kinds of simulation models about the metal foams were summed up, including cubic cell model, Gibson-Ashby model, octahedron model, tetrakaidecahedron model, Voronoi model and 3D random spheres model. The structure?characteristics of each model were described, and the merits and faults of each model?were also analyzed synthetically.
