This contribution gives an overview about the present state of our research in the project B4 in the Collaborative Research Center 398 at the Ruhr University Bochum. The subject of the research topic is the diagnosis and localisation of discrete damage by vibration measurement with the aim of lifetime estimation. First of all, we discuss the verification of eigensystem realization algorithms for system identification. In the second part, a method for finite element model updating is investigated in view of its application for damage localization. A contribution of both methods is validated by means of a numerical example.
