I am a beginner in ABAQUS. Although i learned to model a simple solid RC beam and confidently perform static analysis. However i am unable to simulate nonlinear behaviour. I am trying to use concrete model for calculating stress-strain data. But i am facing the following problems:

1. How to calculate the damage parameters

2. What input do we need to give rather that CDP data.

3. Can any one tell the whole procedure for modelling and analysis.

4. If any one have any excel file for calculation part then please share.
