10. Modeling I

10.1. Characteristics of modeling I

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

10.2. Characteristics of the mesh

The mesh is the same as in modeling \(E\). Recall that it is consistent with the crack.

Volume elements: 804 TRI6.

10.3. Modelling results I

Modeling \(C\) is used as a reference. The response plots for the two models are perfectly superposable.
