Great. This show how the strength increases by deformation.

Thank you very much!! This really helped

A better way to show it would be to see if a shop can take a video of them bending a short piece of .06 6Al4V titanium in a brake to 90 degrees and stop the ram at 90°. Then raise the ram up and measure the angle and it will be several degrees less than 90. The elastic deformation has to be taken into account along with strain hardening when forming metals. It also doesn't have to be a bending type load. We have parts that get formed countersinks and counterbores. The countersinks and counterbores will shrink a good 12 thousandths after the tool forms them.

Isn't elastic deformation the same thing as "springback"?

I am a longhorn, maybe i shouldn't be watching this video lol BUT it really helped. JK :)

Great video but god damn my ears
