Abstract: The energy absorption capacity of vehicles and protective structures has become more important due to ever stringent safety requirement. As an example, increasing focus has been paid to the use of energy absorbing devices in order to overcome the adverse effect of an impact load. Many devices have been designed to study impact energy absorption during a collision and hence protect the vehicle components and passengers. As decades passed on, various types of energy absorbers have been placed in vehicle structures, particularly cars as a significant number of road causalities have been caused by car crashes. Research shows that axial impacts account for approximately 35-40 % of all impacts on a vehicle. In response to this, a comprehensive study have been undertaken to experimentally & numerically investigate axial crushing responses, energy absorption performance of empty & foam filled aluminum concentric tubes with different density of foam. The study was extensively conducted using finite element techniques in conjunction with an experimental set-up& application of available theory.
