I have the values E,k',n' of the curve cyclic Ramberg-Osgood. I would like to know how I can obtain the parameters required Abaqus. Thank you very much everybody!!

I think you need: E, nue, sigma0, n and alpha ... wiki: http://en.wikipedia.org/wiki/Ramberg-Osgood_relationshipand the section in the Abaqus Analysis User's Manual: 19.2.13 Deformation plasticity (in the 6.7EF release at least) There are the equations.
