Conclusion
==========

The structural modification calculation procedure presented here is based on the joint exploitation of the measured data and the numerical model of the modification. It uses the principle of substructuring to couple the two models.

This technique should not be used as a black box. The user must intervene in the choice of the expansion base so that it is as relevant as possible. He must also find the modification that best suits the constraint imposed by the environment where the initial structure is located.

The importance of implementing experimental measurement cannot be overemphasized. Indeed, uncertainties in the experimental data are propagated throughout the calculation and can lead to a significant error in the final results. It is strongly recommended that the person doing the measurement be the same person who is implementing the numerical modeling. It is the most capable of exploiting the measured data, and the most able to perform the coupling between measurement and calculation.
