Proportional limit. Deformation is linear up until this point.

HootinNHollerin@lemmy.world 1 week agoE is where it stops being linear, Y is yield, U is ultimate as in max, and f is fracture / failure. Not sure about p.

P is the Proportional Limit, where it stops being linear, but remains elastic for a short while longer, meaning any deformation can still be recovered. E is the Elastic Limit, where it changes from elastic to plastic
