Reference problem
=====================


Geometry
---------

Material point.


Property of the materials
-----------------------

They are set to :math:`600°C`.


.. code-block:: text

    YOUNG = 145000. ;

    POISSON = 0.34;

    BIGA =9.707593E-08,

    H1ST=0.33,

    H2ST=1.0, K=9.691

    H1=3.E4,

    H2=-280.0, SIG0 =27.9317, ALPHAD =0.5, EPS0 =5.82516E-11

Parameters that manage calculation options:

.. code-block:: text

    DELTA1 =1.0,

    DELTA2 =0.0, S_ EQUI_D =0.0 (the first principal stress is used for the damage calculation)

    KC=0 (variable :math:`\phi` is not taken into account)


Boundary conditions and loads
-------------------------------------

A constant constraint of :math:`\mathrm{160MPa}` is applied from the moment :math:`\mathrm{0,2}h` to the moment :math:`\mathrm{4000h}`.
