For a number of points during a tension test on Man-Ten steel, engineering stress and strain data are given in Table P4.22. 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) Evaluate the following engineering stress–strain properties: elastic modulus, yield strength, ultimate tensile strength, and percent reduction in area.
(b) Determine true stresses and strains, and plot the true stress–strain curve, showing both raw and corrected values of true stress. Also evaluate the true fracture stress and strain.
(c) Calculate true plastic strains for the data beyond yielding to fracture. Then fit Eq. 4.24 to these values and the corresponding corrected stresses, determining H and n.
