5. Conclusion

For D_ PLAN_HM modeling and 3D_HM modeling, the results agree with the analytical solution. For cohesive HM- XFEM Multi-Heaviside elements, the following features are now validated:

• MODI_MODELE_XFEM

• POST_CHAM_XFEM

In the presence of a junction of cohesive interfaces, the cracked bar behaves in compression like a non-cracked bar. The contact is therefore well taken into account in each interface branch and at the junction level.
