8. F modeling#
8.1. Characteristics of modeling#
It is the same modeling as modeling E, but with plane constraints. The intersection is constructed in the same way.
8.2. Characteristics of the mesh#
The mesh, identical to that of modeling B, is represented in FIG. 4.2-a.
8.3. Tested sizes and results#
The movements at the level of the crack lips are tested after having carried out the post-treatment operations relating to \(\text{X-FEM}\) (POST_MAIL_XFEM and POST_CHAM_XFEM). The DX displacement should follow function \({u}_{x}\) in equation 2.2-7. The displacement DY should follow function \({u}_{y}\) in equation 2.2-8. The deformation shown in FIG. 7.4-a is obtained.

8.4. notes#
The remarks are identical to those formulated for modeling E.
