CEE 3020 Civil Engineering Materials Mr. Robert Moser Question 1 The following engineering tensile stress-strain data were obtained for a 0.2% C plain-carbon steel. Engineering Stress (ksi) Engineering Strain (%) 0 30 55 60 68 72 74 75 76 75 73 69 65 56 51 0 0.1 0.2 0.5 1.0 2.0 4.0 6.0 8.0 10.0 12.0 14.0 16.0 18.0 19.0 (fracture) (a) Plot the engineering stress-strain curve, with stress in units of ksi and strain expressed as a %. (b) Determine the ultimate tensile strength of the alloy.

Unformatted text preview: (c) Determine the percent elongation at fracture. (d) Calculate the elastic modulus of the alloy. (e) Determine the 0.2% offset yield stress of the alloy. (f) Make a good estimate the toughness of the alloy. (g) On the graph you have made, schematically show the effect of loading from 0 ksi to 68 ksi, and then unloading completely. (h) Estimate the plastic strain experienced due to the loading scenario described in part (g)....
