Metallic foams are gaining ground as important new engineering
materials.Aluminium foams were produced with different densities using
different percentages of calcium carbonate as a foaming agent. The
mechanical properties of the foamed material were tested using uniaxialcompression
test. Plateau stress σpl, densification strain εd and energy
absorption capacity U, were calculated. The obtained results show that
the collapse strength and the absorbed energy of foams increase with
increasing the density.
