True stress-strain curve of a material

Assignment Help Mechanical Engineering
Reference no: EM13887021

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 ε = 0.03 before being sent to a laboratory for tension testing. The laboratory workers were unaware of the prestrain and tried to ?t their data to Equation.

A. What value of n would they report if they determined n from the elongation at maximum load?

B. What value of n would they report if they determined n from the loads at ε = 0.05 and 0.15?
