Modeling I
==============


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

The characteristics of the :math:`E` model are repeated, with the exception of the cohesive law. We use mixed law CZM_OUV_MIX. Consequently, the mesh of the modeling :math:`E` is made quadratic, and a discretization P2P1 for the contact is defined in the operator MODI_MODELE_XFEM.


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

The mesh is the same as in modeling :math:`E`. Recall that it is consistent with the crack.

Volume elements: 804 TRI6.


Modelling results I
------------------------------

Modeling :math:`C` is used as a reference. The response plots for the two models are perfectly superposable.
