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

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

The modeling is of the BARRE type.

This modeling simulates the relaxation of a cable (class 2, :math:`k1=8.0E-03`, :math:`k2=1.25`), over a period of 4000 hours, with an imposed deformation corresponding to :math:`\mathrm{\mu }=0.75`.


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.
