Load Cycle Modeling

[navash]

Friends,

I want to model a thermal load cycle, meaning I want to apply temperature loads from 0 C to 500 C gradually and slowly back to 0 C. and compare the stresses while temperature increase and decrease. It must show some residual stresses I think.

I have applied till temperature increase. I want to know how to apply the temperature decrease part. Can we do in One Load Step(both increase and decrease), if so how is it and is there any other direct method to do it.

Thanks,

Regards,
Ash
