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.
Material properties in the elastic range: E=75 GPa, v=0.4.

Annealed low-carbon steel has a flow curve with strength coefficient = 80,000 lb/in2 and strain-hardening exponent = 0.25. A tensile test specimen with gage length = 2.0 in is stretched to a length = 3.5 in. Determine the flow stress and average flow stress that the metal experienced during this deformation.
A sheet of aluminium alloy is reduced in thickness by 25% following a
rolling operation. Tensile test specimens were cut from the sheet before
and after rolling. Sketch the tensile test curves for both specimens, making
reference to the differences if any, in Young’s modulus, the elastic limit and
the level of ductility
