hello everyone
I want to model steel fibres reinforced concrete beams in Abaqus, but I don't know how to model it. currently, my little research on the internet showed that I don't need to explicitly model fibres in concrete but I need to take fibres into account in the stress-strain curves.
Now please tell me that along with the stress-strain curve of FRCB's, what other parameters do I need in order to completely model FRCB's.
thank you
Dear Shabir Ahmad
The parameters you need are:
1- Density, Modulus of Elasticity, Poisson's ratio,
2- concrete damage plasticity parameters: plasticity, compressive behavior, and tensile behavior.
thank you, dear Mehran Shahpari , should I find the CDP experimentally, or there exists empirical ways?
Shabir Ahmad
If you want your results to be reliable and accurate, you should have exact parameters for the CDP section in Abaqus. Parameters like inelastic strain (compressive behavior), cracking string (tensile behavior), and their corresponding yield stress.
However, if it is not possible to evaluate these parameters experimentally, you should search and find them from the litrature.
