Tank deformation at elevated temperature

[c8829]

Dear Experts,
I want to know what deformation will be on tank when its heated to 600 °C temperature and air cooled after that. I am using Nastran In-CAD.
I modelled the tank (Carbon steel)and it gave me deformation at 600°C but than problem is how can i save the deformed geometry of the tank and than get the shrinkage while air cooling.
Please help.
Regards.

Hello,

Is there any plastic strain when the tank is heated up to 600deg-C? If so, it should be a good idea to consider different nonlinear steps, first heating the tank and, then, cooling it.

The easiest way to do it is carrying out a 153 - Non-Linear static coupled with heat transfer previously and get the temperature field, which will be applied as a thermal load.

If heating the tank up to 600deg-C does not mean plastic strain, you can simplify the process by getting one temperature field (initial temp of 600deg-C and air cooled define dby it temperature and heat transfer coefficient) and applying it to a static solution (SOL101) as a thermal load.

I hope it helps.
