Crack propagation in ductile materials under monotonic loading

Hello everyone;

 I am Msc student and work on simulation of repairing the cracked steel girders using CFRP in abaqus.

I induce a geometrical crack in steel beam model and exepct it propagate in failure strain path, after increasing the load

I  have a question about crack propagation of steel girder under monotonic loading, what criterion of fracture is suitable for this case?

If i use ductile damage  ti initate crack and growth, how i can obtain require properties such as stress triaxiality,fracture strianand strain rate also has any reference to present the damage evoloution data for ductile steel for instance fracture energy?

Does anyone have experience in this type of simulation? Thank you in advance for your help.

Regards.
