    Specific mechanical characteristics of metal foams in deformation energy absorption are considerable for transportation applications, particularly for construction of crash elements of road and railway vehicles. This paper is aimed at the study of mechanical behavior of aluminium metal foams by modeling their internal structure and analysis using finite element method. Alporas aluminium foam was selected as a reference material and the material characteristics are derived from tensile loading using numerical FEM analysis in ANSYS software. Internal structure is modeled by 2 different methods - using voxel model created on the basis of a series of CT scans and by discretization using Gibson-Ashby's cellular model. Mechanical behavior analysis is performed in both elastic and plastic fields.
