Abstract
The effects of inclusion size on copper shaped-wire drawing were investigated. For this purpose, an experimental investigation for optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, the deformation and the hydrostatic stress of the copper shaped-wire that contain an inclusion were calculated by two-dimensional finite element analysis. As the FEA results, while the leading edge of the inclusion passed through the die, the necking due to inclusion wire drawing occurred on some parts of the copper wire surface in front of and near the leading edge of the inclusion. The effects of inclusion size on drawing stress, tensile stress in front of inclusion and contact compressive stress while copper shaped-wire drawing were carried out. © 2006 Elsevier B.V.
