C modeling
==============

D_ PLAN modeling, with the XFEM method to represent the crack. Quadratic elements TRIA3.


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

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

*NOMBRE OF NOEUDS: 10201*

*NOMBRE OF MAILLES: 20400*

 *TRIA3: 20000*


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

The same quantities as in the B model are tested. The stress intensity factors and the displacement field over a part of the domain are checked in relation to the analytical values.

Note that for the definition of the test zone, for a variable inclination, the modeling approach is generalized A. Depending on the slope of the crack, the corner of the domain opposite to the crack is tested (see [] and []).
