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 highlighted and is marked elastic behavior. The captions on the right are: Linear relationship between stress and strain. Strain is temporary meaning that all strain is fully recovered upon removal of the stress. The slope of this line is called the elastic modulus or the modulus of elasticity.
