E is where it stops being linear, Y is yield, U is ultimate as in max, and f is fracture / failure. Not sure about p.

Rubisco@slrpnk.net 4 months agoGotcha. Thanks! Do the points P, E, Y, U, and F stand for something or are the letters arbitrary?

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

Proportional limit. Deformation is linear up until this point.

Plastic deformation point, elastic deformation point, yield point, ultimate strength, and failure point

And here I was thinking it was: F U, yep.
