**v6.03.133** SSNP133 - Cracking a perforated plate with cohesive models
=================================================================================

**Summary:**

This test makes it possible to model the propagation of two cracks in an elastic perforated plate.

Modeling :math:`A`: Joint elements, cohesive law CZM_LIN_REG

Modeling :math:`C`: Interface elements, cohesive law CZM_OUV_MIX

Modeling :math:`D`: Joint elements, cohesive law CZM_EXP_REG

Modeling :math:`E`: Modeling XFEM, cohesive law CZM_EXP_REG. Mesh conforms to cracks.

Modeling :math:`F`: Modeling XFEM, cohesive law CZM_EXP_REG. Non-compliant triangle mesh.

Modeling :math:`G`: Modeling XFEM, cohesive law CZM_EXP_REG. Unstructured mesh.

Modeling :math:`H`: Modeling XFEM, cohesive law CZM_LIN_REG. Mesh conforms to cracks.

Modeling :math:`I`: Modeling XFEM, cohesive law CZM_OUV_MIX. Mesh conforms to cracks.

Modeling :math:`J`: Modeling XFEM, cohesive law CZM_OUV_MIX. Non-conforming mesh.

The local *ad hoc* numbering of the cohesive elements (except :math:`X-\mathrm{FEM}`) is provided by the MODI_MAILLAGE command and the ORIE_FISSURE keyword. The sudden opening of the cracks is ensured by controlling the load available for each of these laws (see [:ref:`R7.02.11 <R7.02.11>`]).
