Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The forging method with horizontal V-shaped anvils (HVA) is effective in the control of inner stress states, metal tissue, overall properties and geometrical shapes of forgings. FEM numerical simulation is conducted for the HVA forging method to investigate the influence of horizontal angle of HVAs on the stress field in the stretched forging. The simulation results show that during HVA forging, the match of horizontal angle and reduction ratio influences much upon the transversal and axial stress state in the forgings. In order to control the two-way tensile stress, small horizontal angle must be adopted when the reduction ratio is small, while bigger horizontal angle when the reduction ratio is bigger. When the reduction ratio is larger than 15%, it is easy to obtain two-way compressive stress.
