Question

8.41 Using the data in Problem 8.29 and Equations 8.15, 8.16, and 8.18a, generate a true stress-true strain plot for aluminum. Equation 8.18a becomes invalid past the point at which necking begins; therefore, measured diameters are given in the following table for the last four data points, which should be used in true stress computations. Load Length Diameter 46,100 42,400 42,600 36,400 56.896 57.658 58.420 59.182 10.95 10.62 9.40
