This article refers to the metal foam being able to compress "without deforming". Now, I'm no materials specialist, but as a mechanical engineering senior, that makes no sense to me. The whole point of the material seems to be to deform in a predictable and useful manner. Maybe I'm interpreting it all wrong.<p>It seems like the point of it is to absorb as much kinetic energy as possible by deforming, probably from an impact, while slowing the impact to reduce the force and avoiding structural failure.
