Concrete Damaged Plasticity and brittle cracking in Abaqus

[iwealltogether]

I am trying to model a concrete damaged plasticity model and brittle cracking model of reinforced concrete beam in ABAQUS. I am not sure about the background why we need to model these things? I mean what is the objective and scope of modeling such type of beam? What are the results we are likely to observe? What conclusion can we make from designing under such material model? In real life, the beam under extreme loads show inelastic behaviour. Is this behaviour explained by CDP and brittle cracking modeling?
Thanks for your reply.

Is there anyone who can provide me basic idea about concrete damaged plasticity and brittle cracking. What is the objective and scope of such modeling in Abaqus and what results do we expect and compare??I appreciate anyone's idea on this.

How can we visualize crack growth in Concrete Damaged Plasticity Model and Brittle cracking model? I have analysed a reinforced concrete beam under CDP model and brittle cracking model. How can i see the crack pattern and orientation of crack?
Any help will be highly appreciated.
