The average effective strain in a steel stamping is 0.3. If friction is neglected and the stamping is done rapidly, what would be the average temperature rise in the stamping? The effective stress strain law is = 600 (0.01 ) 0.22 MPa; for steel, the specific heat is 454 J/kg/C and the density is 7850 kg/m3. You may assume 100% conversion of the plastic work into heat
