Why the cupping test may not predict well the formability of sheet metals in actual forming processes? Cupping test uses square or rectangular specimens only. Strain in some forming operations is not axi-symmetric. Cupping test is mainly for compression Stress is rarely uni-directional in sheet metal forming.

Can the yield point of material be increased by strain hardening?
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. (a) (b)
