For high strength thick plate, it is difficult to control its springback precisely, because the shell element in traditional stamping analysis software is invalid for thick plate springback. Therefore, the springback of thick plate was analyzed by MARC software with strong nonlinear analysis function. Then, the control points of thick plate springback analysis were summed up by comparing with the characteristics of the thin plate forming, and the general procedure of springback analysis was given. Furthermore, the new analysis method combining methods with die and without die was presented in order to minimize tensile stress caused by the method with die and reduce calculation cost. Finally, the above algorithm was verified by experiment for a longitudinal beam of frame. The results show that the above algorithm can decrease calculation cost and reduce tensile stress. In addition, the springback analysis on brick element is closer to the measured values.
