Based on the Finite Element Theory of Rigid Plastic, relevant problems during plastic simulation on sheet metal forming were technologically studied and simplified; a
simplified model of the blank holder during the drawing process was established and
the effects of related parameters on the forming processes were also studied. At the
same time, a finite-element numerical simulation program SPID was developed. The
distribution of strain and relationship of stress-stroke simulated were compared with
experimented, the results are well coincided with each other. It is verified that the
analytical program is reliable.
