DETERMINATION OF MECHANICAL PROPERTIES OF METAL FOAMS USING MICROSTRUCTURAL MODELS
Abstract
Several different methods for determination of material characteristics have been developed as a result of efforts for cost reduction in cellular materials development and engineering use. This paper is aimed at the study of mechanical behaviour of aluminium metal foams by modeling their internal structure and analysis using finite element method. Firstly, the internal structure was modeled using voxel FE model created on the basis of series of CT scans. However, irregular cell shape and cell dimensions of selected reference material lead to huge and computationally demanding models with limited applicability. These considerations were motivation for subsequent discretization of the internal structure using Gibson-Ashby’s equivalence.
