This calibration work was carried out by my SIMULIA colleagues, Stuart Nixon and Matthew Knight, starting with digitization of the biaxial test data from Figure 1 of the paper cited above.  The target material model for this work is the Abaqus PRF model.  In this use case, the Mullins and Permanent set features are not used. 

These PowerPoint slides give an overview:

Video of the calibration workflow:

The resulting PRF material model looks like this:  (units are N, mm, MPa, degrees C)
