Three-point bending flexural test

[@jasonma4660]

This is helpful. Not much video resource would show the unloading stress distribution after plastic bending

Thank you for the appreciation

very informative. keep uploading such videos.

If the flexural strain formula is valid for only elastic deformation. How can we calculate flexural strain for plastic deformation?
