**"Stress-Strain Curve"**A graphical representation showing the relationship between the change in dimension of the specimen in the direction of the externally applied stress and the magnitude of the applied stress. Values of stress usually are plotted as ordinates (vertically) and strain values as abscissa (horizontally).

A graphical representation relating stress and strain applied to a material

A graphical plot of data obtained from a tensile test, in which the stress on the metal being tested (the force causing the specimen to deform divided by the original cross-sectional area of the gauge length) is plotted against the resulting strain (the extension of the gauge length divided by its original length).
