The results of a tensile test can be evaluated aseither engineering stress-strain curves or true stress-straincurves. The original cross-sectional area of the tensile testspecimen is used to plot the former one, whereas the instantaneouscross-sectional area is used for the latter one. Assume that youare an engineer who needs to design a structural product using ahypothetical metal A, which should not plastically deform in theapplication area. You need to apply a tensile test to thishypothetical metal A in order to determine the required mechanicalproperties. From an engineering point of view, which method youshould prefer to plot stress-strain curve: engineeringstress-strain or true stress-strain? Explain.
