So basically when you bend metal, you're losing some information in the form of broken bonds? Bending enough times in the same location results in enough lost information to result in a fracture?

This is super interesting. Hopefully you don't mind if I continue one more! When you bend the bar and it undergoes plastic deformation, why is it that if you bend the bar enough it will eventually begin to degrade and eventually "fail"? Failure in this context is weaken at the bend or break completely in half.

Based on what I've learned from your posts, it would appear that something happens at the atomic level to the bonds if you overwork the metal.
