Hi,
I am developing a code for a weakly coupled thermal-structual analysis. I perform a transient thermal analysis which gives me the temperature distribution over time, and I calculate the structural deformation based on the temperature change.
Some of the structural material property is dependent on temperature. Since in transient thermal analysis, every node can have different temperatures, how can I handle the assigning of material properties according to the temperature?
Would it be appropriate if I assign the material property at each node acc. to its temperature? Or for each element, I can average the temperature of the nodes and assign the material property to the whole element based on the average temperature.
I am not sure of the best approach. Any suggestions are appreciated!
Thanks,
