Ductile damage modelling in ABAQUS

Hi all

I am M.Sc. sutdent in Istanbul Technical University and my research subject is comparision of several ductile damage models both computationaly and experimentally.

I am trying to compare ductile damage models such as Freudenthal,Cockroft,Ayada ,Brozzo etc. computationally using ABAQUS and seeking a way to implement these damage models in ABAQUS.

To obtain each models damage result individually should damage model be implemented in ABAQUS or can a regular tensile test results be used for calculation of damage values.

Could you please advise me for methodolgy to run a simulation to obtain ductile damage values accordng to models mentioned above.

Thanks in advance for your help.
