viscoplastic anand model

Hello everyone, 

            I would like to know if it is possible to use TBFT option in ANSYS to curve-fit Anand's model parameters using experimental force-displacement data.

     I am aware that the ANSYS manual  has description for hyperelastic and even chaboche model, but is there an established procedure to obtain Anand model parameters using experimental curve fitting ? 

Thank you. 

Hi, all

   I am a newer with ABAQUS. I have to simulate mechanics of a new material with ANAND model.

   I want to know whether a built-in ANAND model was in ABAQUS6.91 right now. And how to use it? I have seen in somewhere that someone said ABAQUS 6.5 had built ANAND model, but I don't find any information about ANAND model in ABAQUS6.91 I am using now.

   I hope you can tell me something about it.

   Thank you very much.
