B modeling
==============


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

Pre-work hardening under tension then cycles with imposed deformation, comparison VISCOCHAB and VISC_CIN2_MEMO. 250 steps of time for 10 cycles.

notes
---------

The difference of :math:`\text{0.8\%}` on the constraints at the final moment fades away if we refine the time step: with a time step twice as fine, the difference becomes :math:`\text{0.4\%}`.
