The curves shown on Figure 2 were obtained from tensile test of two different specimens, SteelA and Steel B. Both of the curves follow the power-law work hardening model o

= Kɛn, whereo and ɛ represent true stress and true strain respectively, K and n are the strength coefficient(MPa) and strain hardening exponent (-) respectively.Determine the values of K and n for steel A and steel B.Include a graph that compares experimental data and fitted curves.
