An Energy Absorption Behaviour of Foam Filled Structures

Aluminium foam is an isotropic permeable metal of cellular construction in the order of 75-85 vol. % of the pores. In turn the mechanical and physical properties depend on the density of foam, i.e. lies in the range in between 0.5-2.1 gm/cm3. Aluminium foam filled structures are used in crash energy absorption, noise absorbing and vibration damping applications. In this article, the compressive deformation behaviour of rectangular aluminium foam filled and rectangular empty mild steel samples are analyzed to identify the supplementary energy absorption rate per unit volume in diverse strain rate, by means of the compressive testing.
