Let me introduce you to another physicist, Robert Hooke (1635-1703), the
author of Hooke's law which simply states that there is a linear
relationship between stress (force applied) and strain (elongation or
compression) produced; that us up to the "elastic limit" where, as you say,
permanent changes occur. Engineers use Young's modulus, "tensile" strength,
"yield" strength and "failure" limit to more finely dice this idea, but
this is, as they say, "beyond the scope of this discussion".

Not only does this work, but it's an environmentally friendly idea that
should charm the pants off the EPA. Since they have run just about every
chassis stripping business out of California, maybe your idea's time has
come. ;-).
