| Abstract: | Experiments were
carried out to generate data on the cold upset forging of square and
rectangular billets of annealed aluminum with different lubricants. The
measured radius of curvature of the barrel was found to confirm with the
calculated value. The calculations were made on the assumption that the
curvature of the barrel followed the geometry of circular arc. It was further
found that the measured radius of curvature of the barrel exhibited a
straight-line relationship against the new geometrical shape factor
irrespective of the shape of the non-circular solid billets. Further, empirical
relations were found to exist between the measured radius of curvature of the
barrel with other variables like hydrostatic stress and stress ratio parameter. |
