EFFECT OF THE DIFFERENT SPEED COMPRESSION ON THE MECHANICAL BEHAVIOUR OF ALUMINIUM FOAM

Abstract

The research is focusing on the improvement of vehicle impact safety considering the mass optimization problem. The application of aluminium foam in the vehicle industry is not a novelty. The crumple parts integrated with metal foam can be one of the better solutions to improve the impact energy-absorbing capacity of the vehicles. However, it is very important that the absorber can hold the mechanical behaviour under low and high-speed impact loads. The present study represents the mechanical behaviour and energy-absorbing efficiency of closed-cell aluminium foam investigated by different compression speeds. The investigation reveals the nexus of the impact speed and the amount of absorbed energy by the foam.
