Crush performance of foam filled tubular structures made of aluminium alloys at different loading conditions

The aim of this research is to develop and characterise square and cylindrical foam filled tubular structures made of aluminium alloys. The thin-walled tubular structures were filled with a closed-cell foam during its in-situ foam formation using the powder metallurgy method. The deformation modes and compressive behaviour were studied using uniaxial compressive tests together with infrared thermography. The results demonstrate that the in-situ foam filled tubular structures have strong bonding and a high ductility that contributes to a progressive and stable axisymmetric deformation under compressive loads without the formation of cracks.
