Abstract:
Virtual die tryout (VDT) technology is a powerful tool for sheet metal forming, compared with the traditional die tryout process. The FEM in the elasto-plastic problems is a basis of this technology. VDT technology and its application in sheet metal forming are described. The FEM program used in this research is the PAM-STAMP.
Key words:
