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


Characteristics of modeling
------------------------

Method GEOMETRIQUE is used by PROPA_FISS to update the crack position.


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

The same mesh as that used for modeling A. is used.


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

We test the values of :math:`{K}_{I}` at each propagation step.


.. csv-table::

    "**Size**", "**Propagation**", "**Reference Type**", "**Reference Value (** :math:`\mathit{Pa}\sqrt{\mathit{mm}}` **)**", "**Tolerance**"
    **(%)**"
    ":math:`{K}_{I}` ", "1", "'ANALYTIQUE'", "''", "32030644,112693", "5.0"
    ":math:`{K}_{I}` ", "2", "'ANALYTIQUE'", "''", "52126536,927129", "5.0"
    ":math:`{K}_{I}` ", "3", "'ANALYTIQUE'", "''", "78186936,734937", "5.0"


The mechanical residual error indicator 'ERME_ELEM' is also tested on the last propagation step (in non-regression only) in order to validate the use of this indicator on 2D models with rotations.
