Modeling C_ PLAN


Characteristics of the mesh
----------------------------

Number of knots: 7030

Number of meshes and types: 160 QUAD8 and 3212 TRIA6

     Length of the first crack :math:`c=\mathrm{0,02}`.

Length of the second crack :math:`a=\mathrm{0,002}`.


Tested sizes and results
------------------------------


.. csv-table::

    "**Size**", "**Reference Value**", "**Reference Type**", "**Tolerance (%)**"
    "G", ":math:`39.098` ", "'NON_REGRESSION'", "-"
    "G_ IRWIN "," :math:`39.093` ", "'NON_REGRESSION'", "-"


The results obtained in this test case are only validated in non-regression.

It is noted that the solution is taken from CASTEM, but the VALE_REFE keyword was not filled in, so we don't know the relative gap between the solution provided by CASTEM and the one provided by Code_Aster.
