Taking the logarithm of both sides of Equation 6.19 yields
Chapter 6, Problem 6.51(choose chapter or problem)
Taking the logarithm of both sides of Equation 6.19 yields log sT = log K + n log PT (6.33) Thus, a plot of log sT versus log PT 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 6.30, make a plot of log sT versus log PT 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.
