5. Conclusion

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

• MODI_MODELE_XFEM

• CHAR_MECA_PRES

• POST_CHAM_XFEM

• the calculation of elementary matrices and vectors in the case where mechanical and hydraulic Heaviside degrees of freedom were introduced in the developments of the HM coupling model.
