Abstract

Quasi-static compression tests for closed-cell aluminum foams manufactured by the melt route were conducted. Deformation mechanisms at the cell level are discussed. Cell shape and the inhomogeneity of the foam structure are considered the primary factors affecting the deformation modes. Four failure modes of closed-cell aluminum foam at the cell/membrane level reveal the mechanisms of energy absorption on the mesoscopic scale. Moreover, the friction between compacting cells helps to increase the energy absorption.
