Deep drawing is a manner of the metal forming, and the most important position in the industry has been occupied because of its high efficiency. In the past, people often used a trial-and-error method and experiences to complete the deep drawing processes.However the time is consuming and the cost is high by this way, so this study adopts the finite element method to simulate the deep drawing forming in order to reduce the processing cost and time, furthermore to predict the thickness distribution of the product and to find the suitable forming parameters. The material properties and forming parameters have the significant influences to the deep drawing forming, such as strain hardening, plastic strain rate, friction and lubrication, blank holder force, radii of die and punch etc. In this study, two popular commercial FEA software, SUPERFORM and DEFORM, have been used to simulate hemisphere deep drawing forming, and the analysis results will be in comparison with experiment results published to verify the correctness of FEM simulations. Throughout this study, the effects of the blank holder force, the radii of die and punch, the gap between punch and die, the frictional coefficient etc upon the maximum forming force and the minimum thickness, are discussed systematically. After a series of simulations, the comparisons between the SUPERFORM and DEFORM show a good agreement with the experiment and the error is very small.

“…Generally it is very difficult to determine the optimum parameters for satisfying the design specification without any problem during the forming process. Now, many researches have been being carried out with the FEA and the optimization techniques [12][13][14][15][16][17][18][19][20][21][22][23][24].…”

A systematic approach of the energy method has been used for analyzing of deep drawing process. The so called simulated annealing algorithm has been used for energy optimization. In this method, the whole deforming region has been divided into five zones. Then the geometry has been expressed by sweeping the section curves defined on the boundary of each zone. The velocity fields have been expressed in a similar manner by sweeping the boundary velocity functions. In every step, the solution has been found through optimization of the total energy dissipation with respect to some parameters assumed in kinematically admissible velocity field defined over each zone. The energy dissipated in the bending zone has been estimated and added to the total energy due to strain and friction energies. In order to check the effectiveness of the present method, deep drawing of circular and square punches have been analyzed and variation of punch load versus punch depth, flange contour and distribution of thickness strain have been obtained and compared with published experimental data. The results show good agreement with the experiment.
