4. B modeling

4.1. Characteristics of modeling

The modeling used is a C_ PLAN modeling.

4.2. Characteristics of the mesh

The mesh is the same as for modeling A.

4.3. Tested sizes and results

We test the values of the stress intensity factors given by the command POST_K1_K2_K3 (analytical comparison and non-regression) and the value of the error estimators for the 3 methods implemented in Code_Aster (parameters ERREUR_ERRE, ERREUR_ERZ1, ERREUR_ERZ2, ERREUR_QIRE,,,,,,, ERREUR_QIZ1, ERREUR_QIZ2) for the primal problem and the dual problem (non- comparison regression).
