Determine the specific energy and actual energy expended for the entire process described in the previous two problems. A metal has a strain-hardening exponent of 0.22. At a true strain of 0.2, the true stress is 137.9 MPa. (a) Determine the stress–strain relationship for this material. (b) Determine the ultimate tensile strength for this material.
