Rules
Past the elastic deformation region / yield stress you get plastic deformation, which even when the stress is completely removed there is permanent deformation.
Gotcha. Thanks! Do the points P, E, Y, U, and F stand for something or are the letters arbitrary?
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.
Proportional limit. Deformation is linear up until this point.
