7. Summary of results

The results obtained make it possible to validate the correct functioning of joint elements with hydro-mechanical coupling with regularized cohesive laws.

The \(A\) and \(B\) models test the compatibility of the joint element with the law CZM_EXP_REG. The results are compared with experimental results. The overall mechanical response of the structure as well as the effect of the loading speed on the flow in the crack are reproduced correctly numerically.

Modeling \(C\), using non-regression tests only, validates the use of the CZM_LIN_REG law. The results are fully in line with what is expected.

Finally, modeling \(D\) makes it possible to test compatibility with cohesive laws in the presence of surface elements HM_DPQ8S that are very poorly permeable in the massif.
