| Abstract: | In this paper,the bulging process of sheet metals in square die, which finds wide application in the present sheet forming industries, is studied by using a thick-shell FEM with large deformation.The calculated results are compared with experimental ones in order to examine the bend effect on the bulging process, and to choose element models correctly. |
