For drucker-prager model, I basically just select the material model in library of engineering data in ANSYS workbench. There is a built-in model which you can define the softenting behavior. However for Solid 65, I know it has to be an inserted command to overwrite the element type. I am not sure how to define the temperature-dependent properties using command though. 

I have seen some videos showing how to use solid 65 to model reinforced concrete. However, since i am studying thermal effect I need to run transient thermal analysis first and then import the result to transient mechanical analysis. That's the difference of my case campared to those traditional analysis.
