Damage Model for Steel in Abaqus

Hi,

I want to try abaqus progressive damage model to simulate steel failure in Abaqus. I read the manual, and found that progressive damage model would be sufficient for my purpose. As I am quite new to damage modeling, I do not know how to determine parameters for shear failure or ductile failure or jjohnson cook model. Also, I would like to use damage evolution as well. Could anyone suggest me some typical parameters for steel (both damage initiation and damage evolution).

Thanks.
