B modeling
==============

D_ PLAN modeling, with the XFEM method to represent the crack. Quadratic elements TRIA6.


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

The unit square is meshed regularly [] .We maintain the refinement of the previous modeling.

*NOMBRE OF NOEUDS: 40401*

*NOMBRE OF MAILLES: 20400*

 *TRIA6: 20000*


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

The same quantities are tested as in modeling A.

Stress Intensity Factors Test:


.. csv-table::

    "**Identification**", "**Reference**", "**Tolerance**"
    "CALC_G ", "", ""
    "K1", "1.00"," 1.0%"
    "K2", "0.00"," 1.0%"
    "G", "1.0 10-5"," 1.0%"


Testing the standard_L2 of the error on the displacement field: :math:`{∥{U}^{\mathit{calc}}-{U}^{\mathit{ana}}∥}_{{L}_{2}}<\mathit{tolerance}\times {∥{U}^{\mathit{ana}}∥}_{{L}_{2}}`


.. csv-table::

    "**Identification**", "**Reference**", "**Tolerance**"
    "POST_ELEM ", "", ""
    "NORME ", "0.00"," 0.1%"


Structure energy test:


.. csv-table::

    "**Identification**", "**Reference**", "**Tolerance**"
    "POST_ERREUR ", "", ""
    "REFERENCE ", "3,50687407712 10-6"," 0.1%"
