Unformatted text preview: of 6 in. to 2 in. Assume that the redundant work is 30% of the ideal work of deformation, and the friction work is 25% of the total work of deformation. 4.- A linearly strain-hardening material with a true-stress-true-strain curve = 5,000 + 25,000 psi is being drawn into a wire. If the original diameter of the wire is 0.25 in., what is the minimum possible diameter at the exit of the die? Assume that there is no redundant work and that the frictional work is 15% of the ideal work of deformation. (Hint: The yield stress of the exiting wire is the point on the true-stress-true-strain curve that corresponds to the total strain that the material has undergone.)...
