Hi everybody!
I have a little problem in performing the simulation of an autofrettaged pipe.
I need first to simulate the autofrettage pressure and thus the stress so created in the walls, and then to apply the working pressure.
The problem is that I am not able to apply the operative pressure into the yet deformed body.
Is there a way to prevent stress the body or imposing the initial conditions of stress and so on?
Thank you for your kind help to the matter
Best regards
Mario
Si avast thank you for your kind help. I'll let you know as soon as I try.
But how can I save the deformed body? Isn't it "enclosed " in a singular simulation study? Do I need to duplicate the study or exists another procedure?
Thanks again
Hi Mario,
I dpoint have SW open at the moment; if my memory serves good, you should be able to save deformed body by right clicking on results folder and the would be an option to save it.
please let me know if you are not able to find it.

Siavash I tried your suggestion but with the option "save deformed shape" I am only able to save the current geometry but not the stress adquiried during the autofrettage process. I don't know how to overcome this problem.
Plus I found in the non linear analysis the possibility to perform a loading-unloading simulation just to simulate the application and then the removal of the autofrettage pressure. But again I find no residual stress in the wall thickness and I cannot plot separately the two phases.
What can I do?
Thank you again for your kind help.

Hi Mario,
Apparently, the save deformed body option that I mentioned is not what you're looking for.
It would be great if you could please upload your simulation files here for further clarification; thereafter, either I or someone else may be able to provide you with an answer.

Mario,
im not sure if this is what you looking for; anyway, here is my initial guess:
you can Perform a simulation with a specified pressure; thereafter, save the deformed body and then perform the second simulation with other boundary conditions on the deformed body.
please let Me know if it helps or you are looking for something else.
Cheers,
