E modeling
==============

This test reproduces bench EPX bm_str_lcab_frot. It validates the use of friction cables in EPX without damping.


Friction material
----------------------

The material BPEL_ACIER is assigned to the cable for Code_Aster and to the friction discretes for EPX with the following parameters:


.. csv-table::

    "FROT_LINE ", "0.018"
    "FROT_COURB ", "0.38"


These coefficients correspond to twice the regulatory friction coefficients of type TICC (Strands Injected with Cement Grout).
