    MODELING OF MACROSCOPIC ELASTIC PROPERTIES OF ALUMINIUM FOAM

  • Original language description

    This paper is focused on the prediction of macroscopic elastic properties of highly porous aluminium foam. The material is characterized by a closed pore system with very thin pore walls and large air pores. Intrinsic material properties of cell wall constituents are assessed with nanoindentation whereas analytical homogenizations are employed for the assessment of the cell wall elastic properties. Very good agreement was found between the various analytical estimates. Two-dimensional microstructural FEM model was applied to obtain effective elastic properties of the upper material level. for which the Young's modulus reached 1.11 GPa. The value is by ~30% lower than the range of experimental values obtained from experimental compression tests. It follows from the 2-D approximation that the 2-D model underestimates the stiffness, by ~30% compared to the real case constrained in 3-D. Therefore, more appropriate 3-D model based on microCT data will be prepared in the future work.
