1) Drawing: Consider a cylindrical rod fabricated from a linear strain hardening material with a constitutive relationship of a=2000 + 20000 € (where o is in psi). The rod is drawn into a wire. If the original diameter of the rod is 0.75 in, what is the minimum possible diameter that can be drawn in the first pass? Assume that redundant work is 20% of the ideal work and that the frictional work is 15% of the ideal work of deformation. What is the drawing force required to complete this operation?

1) Drawing: Consider a cylindrical rod fabricated from a linear strain hardening material with a
constitutive relationship of o=2000 + 20000 € (where o is in psi). The rod is drawn into a wire. If the
original diameter of the rod is 0.75 in, what is the minimum possible diameter that can be drawn in
the first pass? Assume that redundant work is 20% of the ideal work and that the frictional work is
15% of the ideal work of deformation. What is the drawing force required to complete this
operation?
