How apply the three-dimensional constitutive laws instead of uni-axial constitutive laws for confined/unconfined/steel elements in numerical simulation modeling of the reinforced concrete members. Which 3-D models are suitable to apply for this purpose?
Maybe this can help: Article Constitutive modeling of concrete: An overview
Thank you for the article. It contains a lot of references, but, what I need is the application of one famous 3D model in a code as an example.
You can find the C++ implementation of the Menetrey/William model here:

Thank you so much for sharing your valuable program and experience exactly related to the question. I hope I
can use your valuable experience in future for more questions.
I agree that the concrete damage plasticity model is recommended for in Abaqus implicit. Make sure you get a smooth curve and calbrated Hydrostatik hardening.
How will you model the reinforcement and ist interaction with the concrete? Intersiting Simulation....
As you have highlighted you are addressing the answer of @Tareq Hatahet,. Thank you for developing the discussion.
