Steel Stress-Strain diagram. Which of the following statements is NOT correct? Engineering stress is the stress computed using the original area and not the necking down area. The constant stress region is called the yield plateau or plastic range. The linear portion is also called the plastic range. The proportional limit, elastic limit, upper and lower yield points are very close to one another and are treated as a single point called the yield point.
