Assuming that the stress-strain curve in Question 1 is based on engineering stress and strain, how would the true stress-strain relationship look like? will plot a little bit above the engineering stress-strain curve no difference will plot a little bit below the engineering stress-strain curve will plot a bit below at low values of stress and then a bit above at higher values of stress will plot in the opposite direction
