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
A nickel alloy rod specimen having an original diameter of 5.0 mm only experienced an elastic deformation when a tensile load of 2500 N was applied. Calculate the maximum length of the specimen before deformation if the maximum allowable elongation is 0.50 mm.

- 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.
