Can quantum theory explain material elasticity and rigidity?

[Quntapeng]

Can quantum theory be connected with Elasticity theory? I am a graduate student in Mechanics, and I am doing some theoretical/applied elasticity research. And to some extent, I am working with Material Science problems. The relationship of Quamtum Theory with general Mechanics puzzles me. For example, electron cloud or the probability wave of electron can do any effect with the Strength or Rigidity of material?
Thanks for helping!

Check out solid state physics -- many, many references -- and you will find that QM does a great job in explaining many aspects of solids. RA

yes, electron cloud probabilities have a lot to do with solids. It all deals with molecular architecture, VSEPR theory. Look it up, its pleety cool.
