The graph plots stress versus strain. The curve starts at the bottom left of the viewing window at the origin, goes up and to the right with a constant steepness and then goes slightly to the right. The curve then goes up and to the right with increasing steepness, reaches a maximum and then goes down and to the right with increasing steepness and ends at the top right of the viewing window. The nonlinear portion of the curve to the left of the maxima is highlighted and is labeled strain hardening. A caption on the right reads: As the material stretches, it can withstand increasing amounts of stress.
