6. Summaries of results

The objectives of this test have been achieved. The aim was to validate the functioning of the evolution of X- FEM towards multi-cracking. We have seen that two interfaces have been taken into account in several situations: models \(\mathrm{3D}\) and \(\mathrm{2D}\), horizontal interfaces, inclined interfaces, contact without or with friction, etc.

All operators that have undergone modifications for the transition to multi-cracking are operating correctly.
