| Abstract: | ased on the Kirchhoff theory and J2 flow theory,a finite element model has been devel-oped for the simulation of three-dimensional sheet metal forming with total Lagrangian for-mulation. Isotropic hardening and anisotropy along the thickness of the material have beentaken into consideration. The code based on the model was used to simulate the forming pro-cess of an oil box,The results show that the equivalent strain distribution is in conformitywith reality. |
