8. Summary of results

All the PROPA_FISS operator methods used (UPWIND, SIMPLEXE, MAILLAGE and GEOMETRIQUE) made it possible to correctly calculate the position of two existing cracks in the same model and propagating in mode \(I\). The stress intensity factors have been calculated correctly and the methods used correctly calculate the level sets at each propagation.

The results obtained make it possible to validate the implementation of multi-cracking (case of several cracks with a single crack background each) in operator PROPA_FISS.
