Impact Tests of Urethane Foam

The impact behavior of a low-density urethane foam was investi-gated 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...

Description
Summary:The impact behavior of a low-density urethane foam was investi-gated 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 under-bodies of Arctic surface effect vehicles (ASEV) AGAINST THE IMPACT OF COLLISIONS.
