UMAT in ABAQUS

Hi,

I've been learning how to implement material models using UMAT in ABAQUS and I have

some simple questions:

 

I've been trying to implement the viscoelastic models in the paper:

Formulation and implementation of three-dimensional viscoelasticity at small and finite strains

Kaliske, M.; Rothert, H., Computational Mechanics, Volume 19, Issue 3, pp. 228-239 (1997) .

 

Nonliear UEL and UMAT

Dear friends,

     Is it possible to call nonlinear UEL and nonlinear UMAT for the same problem in ABAQUS?
