The Influence of Cell Shape Anisotropy on the Tensile Behavior of Open Cell Aluminum Foam

Tensile tests have been performed on annealed (AN) and heat treated (HT) Duocel open cell aluminum foam (20 PPI) samples for relative densities ranging between 3 and 13%. The long axis of the cell was oriented longitudinal (LD) or transverse (TD) to the loading direction to observe the effect of the cell shape anisotropy on the tensile behavior. During the tensile tests the evolution of damage was monitored by measuring the electrical...
