Which material model was used?  Remember that the metal plasticity material models assume the the plastic strain region slopes do not curve down and turn negative.  This is a theory assumption.  The second question would be what is the material test data format - engineering or true stress-strain.  If engineering did you transform it for input into Ansys WB Engineering Data?  And did you solve this with large deformation turned on?
