Abstract

Due to their unique properties metallic foams are promising material components for various industrial applications, such as in the automotive industry, as well as in power sources (Ni battery electrodes). Experimental evidence has documented that during compression of metal foams, deformation is governed by the development of horizontal localization bands; cell failure (brittle fracture or plastic buckling) occurs within the bands leading to the collapse of the material. In the present study cellular automaton numerical simulations are performed to model the damage evolution during compression and to predict the stress-strain response. The simulation predicted stress-strain curve is found to be in very good agreement with experimental stress-strain data obtained for Al foams.
