D modeling
==============


Characteristics of modeling
-----------------------------------

The modeling is the same as modeling A, but with 2 different behaviors (both integrated implicitly): VISCOCHAB and VISC_CIN2_MEMO, to validate that the memory of the greatest work hardening is taken into account.

notes
---------

Both behaviors give identical results on all components, except for the internal variable :math:`{\xi }_{\text{xx}}` (difference of 0.2%). This difference decreases when the time discretization is refined.
