| Abstract: | Based on the continum mechanics and finite deformation theory, a finite element model for simulating the three dimensional sheet forming process has been established. A finite element analysis program DESSFORM3D for the simulation of sheet forming process using dynamic explicit integration is developed. Finally, the deep drawing process of hemispherical parts under different blankholder conditions is analyzed by using the new dynamic explicit/elasto viscoplastic finite element program developed by the authors. The numerical results are compared with the experiments to verify the calculated results of the program. |
