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 \(A\): Joint elements, cohesive law CZM_LIN_REG
Modeling \(C\): Interface elements, cohesive law CZM_OUV_MIX
Modeling \(D\): Joint elements, cohesive law CZM_EXP_REG
Modeling \(E\): Modeling XFEM, cohesive law CZM_EXP_REG. Mesh conforms to cracks.
Modeling \(F\): Modeling XFEM, cohesive law CZM_EXP_REG. Non-compliant triangle mesh.
Modeling \(G\): Modeling XFEM, cohesive law CZM_EXP_REG. Unstructured mesh.
Modeling \(H\): Modeling XFEM, cohesive law CZM_LIN_REG. Mesh conforms to cracks.
Modeling \(I\): Modeling XFEM, cohesive law CZM_OUV_MIX. Mesh conforms to cracks.
Modeling \(J\): Modeling XFEM, cohesive law CZM_OUV_MIX. Non-conforming mesh.
The local ad hoc numbering of the cohesive elements (except \(X-\mathrm{FEM}\)) 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 [R7.02.11]).
