ALUMINIUM FOAM: PREDICTION OF MACROSCOPIC ELASTIC PROPERTIES USING NANOINDENTATION AND UP-SCALING MODEL
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 ranges from 1.11 GPa to 1.4 GPa depending on the size of the evaluated area. The estimated range of values was lower in comparison with experimental results obtained from experimental compression tests. It follows from the 2-D approximation that the 2-D model underestimates the stiffness, compared to the real case constrained in 3-D. Therefore, more appropriate 3-D model b
