Thank you so much dear Peteroznewman for your quick reply. let me paraphrase, Imagine that you have a bent shaft that is straightened and now you want to monut a diak by shrink fit on it. to do so you need to first bend the shaft and obtain residual stress, then you should apply this stress on a straight shaft in the second analysis. ok? I dont wanna compound two stresses, If I wanted to do so the job was so straightforward and could be done in 2 load steps. In fact I want to model shrink fit in a shaft cut from a prestressed metal 

Thanks a millionÂ
