Research on applying one-step simulation to blank design in sheet metal forming

Applying one-step simulation to blank design in sheet metal forming was investigated. The authors have put forward and fulfilled the idea that blank design should combine with the material properties and other industrial art conditions. The blank design for various depths of square box was also completed. The results that were compared to those obtained by DYNAFORM showed that the blanks designed through one-step simulation method are reasonable. The study of an industrial example also indicates that the one-step simulation method can be used in large size auto-panel blank design.
