The impact behavior of a low-density urethane foam was investigated experimentally, and the crushing characteristics of the rigid closed-cell foam were determined as a function of impact velocity, foam sample thickness, and temperature. The dynamic crushing strength of the material was found to be much better than its static strength. This energy-absorbing capability allows consideration of the foam as protection for the underbodies of Arctic surface effect vehicles (ASEV) against the impact of collisions.
