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


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

     Law of nonlinear elastic behavior (*' ELAS_VMIS_TRAC '*)

**Loading:** Next bending moment (:math:`-Y`) distributed across the face of the upper pipe.

:math:`M=-5216\mathit{kNm}` where :math:`M` is the moment on the :math:`Y` axis.


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

Number of knots: 40069

Number of meshes and types:

 *3D_SI*: 8450 TETRA10 and 5580 HEXA20

 *3D*: 240 PENTA15, 295 PYRAM13


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

The value tested is the local energy release rate :math:`{J}_{\text{fond}}` on the node at the bottom of the crack. (option G from CALC_G). This value is tested for an integration ring defined by NB_COUCHE_INF =2 and NB_COUCHE_SUP =5.
