As importance of ultrasonic guided waves is growing rapidly, new signal evaluation techniques occur almost on a regular basis. Unfortunately, they often lack real data testing or at least comprehensible data acquisition.
To enable comparisons of evaluation methods on a mutual basis, this website provides a transparent data set of real wide-range measurements. As it is freely available we explicitly encourage everyone to test their own algorithm with the provided data and include the results in their publications.
Who We Are
Inquisitive people keeping themselves busy with problems of structural health monitoring and guided waves join together in an expert committee under the patronage of the Deutsche Gesellschaft für Zerstörungsfreie Prüfung e.V. (DGZfP). Therein the working group signal processing pulls together those who sympathise especially with processing of guided wave signals. For now, three regions of interest are investigated precisley:
Accurate imaging techniques enable a precise damage localization and targeted maintenance actions.
Wave Field Analysis
Acoustic wave field analysis helps understanding the nature of guided wave propagation and provides necessary information for reliable damage characterization.CONTACT
Environmental & Operational Effects
For a robust and practical guided wave SHM system all potential environmental effects on the system have to be taken into account.CONTACT
For now the team includes researchers from the following institutions and companies:
Frankfurt am Main
Faserinstitut Bremen e.V.
Deutsches Zentrum für Luft- und Raumfahrt (DLR)
Fraunhofer-Institut für Keramische Technologien und Systeme IKTS
Bundesanstalt für Materialforschung und -prüfung (BAM)
The samples were produced according to the high standards of aerospace requirements.
X-ray imaging and ultrasonic inspection assure the integrity of the samples. Material properties are provided.
Propagation behaviour of guided waves in the samples was recorded using a 3D laser Doppler vibrometer.
Guided waves signals were recorded for a large setup of frequencies and artificial defects in a controlled environment.
