Abstract

The paper gives a short overview of geometrical characterization, experimental testing, computational modelling and finite element analysis of various cellular metals: Advanced Pore Morphology (APM) foam, open-cell aluminum foam, Metallic Hollow Sphere Structure (MHSS) and cellular metals with uni-directional pores (UniPore). The geometrical analysis and characterization is based on the analysis of micro computed tomography scans and proper recognition of their internal cellular structure, taking into account statistical distribution of morphological and topological properties. The results of conducted geometrical analysis provided means to develop methodology for proper 2D and 3D geometrical modelling of irregular cellular structures and consequent formation of computational models. These were used to study the compressive and bending behavior of analyzed cellular structures by means of quasi-static and dynamic nonlinear computational simulations (using engineering codes ABAQUS and LS-DYNA), validated by experimental tests.

各种类型多孔金属的几何和力学分析
本文简要介绍了各种多孔金属的几何表征、实验测试、计算建模和有限元分析:先进孔形态(APM)泡沫、开孔铝泡沫、金属空心球结构(MHSS)和单向孔多孔金属(UniPore)。几何分析和表征是基于对微观计算机断层扫描的分析和对其内部细胞结构的适当识别,考虑到形态和拓扑特性的统计分布。所进行的几何分析的结果提供了方法,以发展适当的二维和三维几何建模不规则的细胞结构和随之形成的计算模型。通过准静态和动态非线性计算模拟(使用工程代码ABAQUS和LS-DYNA)对所分析的细胞结构的压缩和弯曲行为进行了研究,并通过实验测试进行了验证。
