Initial stress and strain in ANSYS

Hi everybody,

 i?m simulating a manufacturing chain finite elements analysis. Every step of this chain have been developed by different software. I use ANSYS. Somoone know how to impose the initial strain and stress state deriving from previous simulations to my ansys model: I'm able to use INISTATE command but only stresses are imported, I loose initial strain info: are they important if my material is elasto plastic? how i can resolve the problem?

Thanks in Advance Michele
