| Abstract: | Based on the continuum mechanics and finite element theory.A finite element model has been established by using the dynamic explicit algorithm,and the stamping process has been simulated by using ANSYS/LS-DYNA program.With three varied loading routes,variational rule of maximal stress in the direction of deep drawing and thickness of the round sheet-metal blank have been studied,and influence of forming quality has been analyzed.Results obtained can be a guidance of production. |

| Keywords: | Deep drawing Dynamic explicit algorithm ANSYS/LS-DYNA Forming quality |
