For a number of points during a tension test on Man-Ten steel, engineering stress and strain data are given in Table. Also given are minimum diameters measured in the necked region in the latter portions of the test. The initial diameter was 6.32 mm. (a) Determine the Young’s modulus; (b) Determine the true stress and strain throughout; (c) Calculate the true plastic strain for the beyond yielding.
