Hi all...
I am modeling Reinforced concrete beams using ABAQUS. I used SMEARED CRACK MODEL to model concrete. The thing is i am not able to get the POST-PEAK behavior. Hence i went for CONCRETE DAMAGE PLASTICITY MODEL. The journals i referred briefs about the constitutive relation for this model but not how to arrive at the values of the stress-strain curve for the Concrete Damage plasticity model.
Please help me out in this regard as early as possible.
Thanking you in advance.
With regards
Srividhya
