In order to evaluate the crash safety of automobiles, various collision tests have been performed. In the offset frontal collision test and the side collision test, which simulate car-to-car crashes, the deformable target is a honeycomb material made of aluminum sheets. The impact absorption property of the honeycomb material depends on various parameters. In this study, these influential parameters (the collapsing velocity, the air pressure inside hexagonal cells, the honeycomb geometrical shapes and the delamination force of cell walls) were investigated with the falling weight tests and the finite element simulations. The obtained results are shown as follows; High collapsing velocity increases the impact collapsing load in large deformed region. In more than 40% deforming ratio, the air pressure change inside the hexagonal cell influences the impact collapsing load. The specimen height does not affect the impact collapsing load directly. The experimental static/dynamic ratio of honeycomb collapsing load was 1.5.
