Dear all,

I am trying to learn how to creat damage plasticity modeling for reinforced concrete at high temperature.

I was trying to use concrete material with Drucker-Prager softening material model in ANSYS library, but came with convergence issure when applying high temperature to the model. Has anyone tried similar approach as mine?

Also, I noticed that a lot of discussions mentioned that solid 65 handles concrete plasticity pretty well. However, it required a command input to each body while using workbench (I amusing Transient Structural). So I am wondering if there are any ways to define different stress-strain relationship at different temperature in Solid 65 model?

Hi I am a fellow learned to Ansys however did you use commands to make your concrete model ?

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.

Oh ok i understand i guess i only know about the basic stuff 
Glad you moving forward though
