C modeling
==============

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

The modeling is of the BARRE type.

This modeling simulates the relaxation of a cable with variable deformation over a period of 6 years. On the range [:ref:`0,1an <0,1an>`] imposed deformation :math:`{\mathrm{\epsilon }}_{0}` corresponding to :math:`\mathrm{\mu }=0.75`, on the range :math:`\left]1\mathit{an},3\mathit{ans}\right]` imposed deformation of :math:`1.025\ast {\mathrm{\epsilon }}_{0}`, on the range :math:`\left]3\mathit{ans},6\mathit{ans}\right]` imposed deformation of :math:`1.050\ast {\mathrm{\epsilon }}_{0}`. The deformation jump is applied in 1 hour.


Characteristics of the mesh
----------------------------

The mesh contains 1 element of type BARRE.

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

The quantity tested will be the stress in the bar, at various times.
