    Gotcha. Thanks! Do the points P, E, Y, U, and F stand for something or are the letters arbitrary?

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

      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.

        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.
