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 linear portion of the curve is labeled elastic behavior. The region transitioning from linear to nonlinear is labeled yield. The nonlinear portion of the curve to the left of the maxima is labeled strain hardening. The maxima is labeled ultimate strength. The nonlinear portion of the curve to the right of the maxima is labeled necking. The end point of the curve is labeled fracture stress.
