A rectangufar workpiece has the following original dimensions: 2a = 120 mm, h = 40 mm and width = 25 mm
(see Fig. 6.5). The metal has a strength coefficient of 530 MPa and a strain hardening exponent of 0.26. It is
being forged in-plane strain with u = 0.25. Calculate the force required at a reduction of 25%. Use the average-

P Flag question
In a slab rolling operation, the maximum thickness reduction (del hmax) is given by del hmax = μ²R, where R is the radius of the roll and u is the coefficient of friction between the roll and the sheet. If µ = 0.1, find the maximum angle subtended by the deformation zone at the centre of the roll.
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.
