Most papers says that they are modelled elastic until failure
How to use Abaqus material library to simulate GFRP material using say Young 's modulus 50 GPa and compressive strength 700Mpa and tensile strength 800Mpa?
First, you need to add new material (GFRP) to the library. For doing this, you can check the link below:

After that, you should assign the new material you just added to your model. In order to do that, you can check the following link:
https://abaqus-docs.mit.edu/2017/English/SIMACAECAERefMap/simacae-t-prplibraryuse.htm
I also did this type of numerical analysis. However, it was a very complex input material. Actually, there are some training videos on youtube and you can following them. It may faster.
You have the Young's Modulus, Tensile strength and the ultimate strain of rebars, say 2.61% or 1.46%. easily define the line.
