    Ah yes the part of the curve where the stress permanently changes you. Yeah, accurate.

    this assumes a ductile material. I myself am smiling as though everything is fine in the elastic region and may snap at any moment.

    Can a TI-84slinger explain this for us pipette-wielders?

      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?

          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

      Everything past the dotted line is the point where the material won’t go back to its original shape.
      Example: You can push on the hood of your car all you want, it’ll flex, and go back to its original shape (elastic deformation); but stand on it, and it’ll dent (plastic deformation).

    The material is too ductile. I am at the peak of a narrow yield curve and then, snap, material breaks.
