M.Ing. / To investigate the effect of plastic anisotropy in 1200H14 Aluminium sheet, simulations of the Swift Cupping Test were carried out using the finite element program ABAQUS. Anisotropy was built into all simulations based on the plastic strain ratio which was calculated from tensile tests on specimen cut in three directions in the plane of the sheet. Deep drawing tests were carried out using a punch and die sub-assembly as described by the Swift Cupping Test. Holder loads were kept constant while the punch load and displacement were recorded. Punch force-punch displacement curve and the formation of ears were compared with experimental results.
