Metallurgy, slip planes, shock theory...

[392hemi]

I read in an old metal working book that when a auto body panel is struck sharply with a hammer that for a microsecond or nanosecond there is a vibration or "shock waves" that allows the grains of metal to slip past one another and re-arrange slight. I am desperately looking for an explanation for a chapter in a book I'm writing.

Can anyone in this forum help? Or does anyone have a suggestion where to find help?

Thanks,

The college course title is "Materials Science." A google search will turn up a bunch of sites, but real quick I found THIS (http://www.mae.cornell.edu/zabaras/Courses/MAE212/MAE212.html#lectures) one. Lecture 13 discusses slip planes and deformation.
