Example of use in 3D
---------------------------

Take the case of a mesh crack:

The crack background is defined in DEFI_FOND_FISS:

.. code-block:: text

ff= DEFI_FOND_FISS (MAILLAGE =MA,

     FOND_FISS =_F (GROUP_MA = 'LFF'),

         )

Examples of calculating the energy return rate in 3D (local):

.. code-block:: text


    G1 LOC = CALC_G (OPTION = 'G',
RESULTAT = water,
THETA = _F (FISSURE = ff,
R_ INF = 1. ,
R_ SUP = 2. ,
DISCRETISATION = 'LINEAIRE'),
)

Example of calculating stress intensity factors in 3D:

.. code-block:: text


    KLOC = CALC_G (OPTION = 'K',
RESULTAT = water,
THETA = _F (FISSURE = ff,
R_ INF = 1. ,
R_ SUP = 2. ,
DISCRETISATION = 'LINEAIRE'),
)
