Detailed Analysis of Closed‐Cell Aluminum Alloy Foam Internal Structure Changes during Compressive Deformation

This paper proposes the new methodology for geometrical properties identification of step‐wise deformed closed‐cell aluminum alloy foam. The change of internal structure of cylindrical foam specimens during deformation is ex situ recorded by a micro computed tomography scanner. The geometry of five specimens is analyzed in un‐deformed and several deformed states until 70% of engineering strain. The obtained CT images is used to construct the 3D...
