The true stress-strain curve of a material obeys the power-hardening law with n = 0.18. A piece of this material was given a tensile strain of e = 0.03 before being sent to a laboratory for tension testing. The laboratory workers were unaware of the prestrain and tried to fit their data to Power law. What value of n would they report if they determined n from the elongation at maximum load? What value of n would they report if they determined n from the loads at e = 0.05 and 0.15?
