dc.description.abstract | The numerical simulations of the high-velocity impact forging processes are described in this paper. The explicit time integration finite element method was used to compute the deformation of the workpiece and the dies. In order to consider the effects of strain hardening, strain rate hardening and thermal softening, which are frequently observed in high-velocity deformation phenomena, the Johnson-Cook yield surface model was applied Through the copper blow test simulation, the developed program was verified, Also, the developed program was applied to simulations of high-velocity multi-blow forging processes. Two types of workpiece configurations, cylinder and block, were used for high-velocity multi-blow forging simulations. As a result of multi-blow forging process simulation, it was found that the change of the blow efficiencies and the clash load generated by the blow operations could be efficiently analyzed. | - |
