Taking the logarithm of both sides of Equation 6.19 yields

Taking the logarithm of both sides of Equation 6.19 yields

Thus, a plot of log sT versus log ?T in the plastic region to the point of necking should yield a straight line having a slope of n and an intercept (at log sT = 0) of log K.
Using the appropriate data tabulated in Problem 6.29, make a plot of log sT versus log ?T and determine the values of n and K. It will be necessary to convert engineering stresses and strains to true stresses and strains using Equations 6.18a and 6.18b.
