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

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

The modeling is BARRE.

This modeling simulates the relaxation of a cable (class 1, :math:`k1=6.0E-03`, :math:`k2=1.10`), 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.
