Before defining the stress-strain curve, you must first understand what is stress and strain. Stress is defined as the ratio of the force divided by the cross-sectional area of the material to which the load is implemented. A Strain refers to the measure of the deformation of the material because of the applied force.
Now, the Stress-Strain curve is the graphical representation of the behavior of a material when the force is applied. In short, it is the curve that is produced by plotting stress and strain values under different loads. The fig is shown below:
