铝合金拼焊板技术还存在许多问题，如成形极限、起皱、回弹、焊缝位移、焊接质量等有待研究；
Other factors include: welding metallurgy quality, direction of the main strain, ratio of thickness, ratio of intension, location of welding line, displacement of welding line, etc.
将这些位移作为边界条件输入有限元模型中计算毛料应力、应变和回弹。
The calculated end displacements are input into the FE model as boundary conditions to compute the stress, strain and springback of the workpiece.
