子控制

Numerical simulation is carried out by finite element inverse approach. The initial blank shape and stress, strain states have been obtained. At the same time, the formability of the fender has been analyzed. The possible defects in the sheet metal forming process are estimated, and several ways are provided to prevent and control these forming defects.
