Project description
The aim of the project is to develop and validate the electromechanical impedance method (EMI) as a method for condition monitoring and damage localization at rail support points of bridge structures. EMI spectra are to be used to reliably detect different damage scenarios such as loss of prestressing force, saw cuts and cyclically initiated cracks. In addition, the influence of varying environmental conditions, in particular temperature, on the measurement results will be investigated and taken into account using suitable compensation approaches.
