Question
The data shown in the table below were obtained from a tensile test of high-strength steel. The test specimen had a diameter of 13mm and a gage length of 50mm. At the fracture, the elongation between the gage marks was 3.0mm and the minimum diameter was 10.7mm.
Plot the conventional stress-strain curve for the steel and determine the proportional limit, modulus of elasticity (i.e the slope of initial part of the stress-strain curve), yield stress at 0.1% offset, ultimate stress, percent elongation in 50mm, and percentage reduction in area
