6. D modeling#
6.1. 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.
6.2. Tested sizes and results#

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