Stress-Strain Curve From Load-Deformation Curve  
scene 7 of 7

The load-deformation plot and the corresponding stress-strain diagram are shown below. Material properties that are essential for engineering design are obtained from the stress-strain diagram.

Interpretation of the stress-strain curve is discussed in a companion movie.

The graph plots the load in pounds versus the deformation in inches. The vertical axis ranges from 0 to 16,000 pounds and the horizontal axis ranges from 0 to 0.5 inches. The graph starts from the bottom left at the origin, goes up and to the right with very high steepness till the point (0.025, 12,000). The graph then goes up and to the right with constant steepness till (0.25, 14,200). The graph then goes down and to the right with approximately constant steepness till (0.4764, 13,620). All values estimated.
