CDP model used in Abaqus 2

[compe_ad]

Can you please recommend me any useful material that will help me to understand CDP model generally used in ABAQUS for concrete materials? I have read some fundamental papers like Lee and Fenves, Lubliner et. al., etc. to understand the theory behind it. I got it to some extent. Now, I am looking for something that describes CDP from practical point of view. My main goal is to understand the output that I am getting from my analysis.
Any sort of information will be greatly appreciated.

Thanks for sharing. It explains how to define CDP for concrete, but it doesn't have tutorials which explains how CDP works. I found one tutorial (see attached link) which explains CDP in very brief but, unfortunately, it is not in English language. I am looking for similar kind of tutorials.

Read the Abaqus Theory Guide, in the official Abaqus Documentation, if you want to understand CDP. The constitutive equations can be manipulated however you need, but it's a bit hard to grasp if you haven't had coursework in elasticity and plasticity w/ continuum theory. The only "practical" advice I can give is that the damage propagation is mesh dependent and the model runs best if the reinforcement bars are modeled as line elements, using the embedded element constraints, not solid. That means your slab, beam, wall or whatever should not be meshed to be only 1 element thick.

I used to use this metal bar slamming into a reinforced concrete wall as a teaching example around 10 years ago. There are a lot of resources out there on CDP. It runs pretty slow compared to a lot of other constitutive models available.

I found this Abaqus manual free to access:

Thanks! You understood me well. I haven't taken coursework related to plasticity before.
I am open to learn relevant theories that is necessary to understand CDP. Please recommend if there is any simplified version of literature.
