No there isn't, I got a good understanding during my 2 engineering degrees, PHD and 15 years in industry

The forces applied to a hook run pretty much straight down the shank, as long as the bend is still tempered correctly then no problem - that's why I said clamp the hook into something metal as a heatsink - so the bend won't be effected. Annealing the eye really won't make a great deal of difference to the performance of the hook. You can't apply enough force to straighten the eye out because there are no significant moments present - you certainly couldn't do it in a real life fishing situation.
Oh and work hardening raises the yield strength
