In the input deck, simply include a *INTERFACE_SPRINGBACK_SEAMLESS control card. Make sure to add proper constrains to remove rigid body motion under this card. LSDYNA (950 or newer) will eliminate all rigid bodies and perform springback analysis at the end of forming. Other springback control cards (*CONTROL_IMPLICIT_xxxx) can be added if necessary.
