The hypervelocity impact behavior of aluminum foams was investigated numerically and experimentally. These foams have homogeneous open‐porosity, cell sizes about 1.6mm and relative densities near 26.9%. Several light gas gun experiments were performed, with bumpers containing aluminum foam. The aluminum foam can effectively absorb and scatter the impact energy of projectiles. The foam is discretised with Smoothed Particle Hydrodynamics particles for the numerical simulations.
