Modeling A
==============


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

Material point, behavior VISC_MEMO_NRAD.

Each elementary cycle (a traction-compression for a given twist) is discretized in 48 steps. To perform a complete turn on the previous diagram you need :math:`360\mathrm{/}15\mathrm{=}24` elementary cycles.

We complete 4 full laps in total, for a total of :math:`48\mathrm{\times }24\mathrm{\times }4\mathrm{=}4608` time steps.


Tested sizes and results
------------------------------

The representation of the results in a :math:`\sqrt{3}{\sigma }_{\mathit{xy}};{\sigma }_{\mathit{xx}}` diagram shows the stabilization of the response
