Talk:Strain energy

This is a pretty simple definition of strain energy, considering that stress (sigma) and strain (epsilon) are both tensor quantities. They also don't need to be constant throughout an object. I see that this page is listed under chemistry rather than solid mechanics, so maybe in this application the definition is simplified. Generally, though, the strain energy of a solid is the volume integral of 1/2 times the stress tensor double dotted with the strain tensor (Section 10.5 of Structural Analysis by Bauchau and Craig).

that was a rather science based definition of strain energy. anyone know the definition of strain energy, and its formula? I dont know

So is strain energy the enrgy that holds things together? The bonds between the particles that enable things to hold their shape, and thus when other types of energy are acting upon it then the strain energy is affected and the shape distorts? —Preceding unsigned comment added by 81.104.44.143 (talk) 09:47, 15 September 2007 (UTC)
