J modeling
==============

Closed crack bottom, calculation of :math:`G` for incompressible elements.


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



      Identical to modeling A except the elements used are 3D_ INCO_UPG.


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

Identical to modeling A


note
--------

The keyword SYME is used in the CALC_G operator to automatically multiply by two the energy restoration rate calculated on a single lip of the crack, when the FOND_FISS operand is absent. When FOND_FISS is present, symmetry information is retrieved directly from the fond_fiss concept created via DEFI_FOND_FISS.


Tested sizes and results
