| Abstract: | ![]()
A comparison research about the implicit and explicit solutions of sheet forming simulation was presented. On the platform of Autoform and Ls dyna3D, a dynamic forming simulation of a sideframe, of Santana 2000 was done, and the engineering strain, the thickness distribution and the FLD between the two softwares were compared. It indicates that their results coincide with each other very much and the areas of the wrinkle and failure are the same roughly. Further, the characteristics of the two softwares in geometric model and preprocessing of the finite element were discussed and the questions which need attention provided. |
