Determination of Mechanical Properties of Metal Foams using Microstructural Models
Original language description
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. Investigated mechanical characteristics are particularly the evolution of overall Young's modulus according to different relative densities and in the plastic field tensional stress-strain diagram. The beam-only discretization is considered intentionally to investigate its suitability for modeling of closed cell foams. Finally, FEM numerical results are compared to Gibson-Ashby's mathematical model.
