Identification of micromechanical properties on metal foams using nanoindentation
Result description
This paper is focused on the identification of micromechanical properties on highly porous aluminium foams. The material is characterized by a closed pore system with very thin pore walls and large pores. Intrinsic material properties of cell wall constituents are assessed with nanoindentation whereas analytical and numerical homogenizations are employed for the assessment of the overall wall elastic properties. The Young's modulus was found to be close to 70 GPa for the studied aluminium alloy irrespective to the used homogenization procedures.
