u2.06.42 Implementation of modal adjustment procedures

Summary:

In this document, modal adjustment techniques are presented. Modal readjustment consists in exploiting the specific modes of the structure in order to obtain a numerical model that best reflects the dynamic behavior of the structure under study.
