A steel specimen of rectangular cross section with 120 mm width, 180 mm thickness and 90 mm height was upset at room temperature by open-die forging to a height of 55 mm. If the strength coefficient and strain hardening exponent of this material were l1015 MPa and 0.17 respectively, the coefficient of friction is 0.2, and assuming that the thickness would not change during forging; determine the required upsetting force at the end of stroke.

A long, copper strip, 500 mm wide, 3 mm thick, was found to have 450 MPa yield stress. The strip is required to be rolled in order to reduce its thickness. In the rolling process, the width remains practically unchanged while the rolls apply pressure in the thickness direction. An additional tension of 150 kN is applied in the longitudinal direction to assist the forming process. Ignoring the change in the width and any friction effects, determine what roll pressure would just cause deformation: according to the Von Mises yield criterion. according to the Tresca yield criterion.
