Keywords: aluminium foam, shock wave, critical impact velocity, finite element method

The impact response of aluminium foam and its dependence on relative density and impact velocity are analyzed. The simulation results show shock enhancement of the cellular structure becomes more significant with lower relative density and high impact velocity. The estimated shock front velocity increases with impact velocity and relative density.
