Jul 24, 2010 · I am currently researching impact attenuation and I am having some difficulty determining what exactly the difference between the compressive and crush strength of a material is. It would seem nearly logical to reason that they are the same thing, but I have been told that they are not and considering that one involves the dissipation (or lack there of) of a more sudden impulse of energy and ...
