Xizhang Chen

Of couse possible.

Edward Andrew Payzant

Xizhang Chen is absolutely right. It is not only possible, but there are many published examples of such FE models - just search the literature. Here is one paper for which I contributed experimental data (the FEM work was done by Dr. Bostjan Taljat, who was at ORNL at the time):

Dear Sir,

Do you consider residual stress as a result of thermal stress?

Or you consider residual stress because of the manufacturing stress( except thermal working)?

May you clear up with further information to decide which method is convenient for your case.

Regards.
