8. Development prospects

In conclusion, the numerical implementation of the large slippage approach with X- FEM has been validated under the conditions set out at the beginning of this document. The approach can therefore be used with friction in Code_Aster in 2D (plane stresses and plane deformations for element types TRI3, QUAD4, TRI6 and QUAD8) and in 3D (for elements HEXA8, PENTA6 and TETRA4) and in 3D (for elements, and). The approach has also been generalized at the bottom of the crack.

The large sliding approach with X- FEM is also validated for multi-cracked elements (junctions in particular) without friction in 2D and 3D. However, efforts remain to be made to ensure the robustness of the method in this case.
