**u2.07.03** Conducting a structural modification study using measured data
=============================================================================================

**Summary:**

The purpose of this document is to describe the implementation of a structural modification study based on measured data. The method used is based on the substructuring technique. The first substructure (initial structure) is obtained from the eigenmodes identified experimentally and the second substructure (modification made) is modelled numerically by finite elements.
