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:
Imaging
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.
CONTACTEnvironmental & Operational Effects
For a robust and practical guided wave SHM system all potential environmental effects on the system have to be taken into account.

DATA SET
A First Step to Increase Comparability
We aim to provide a reliable and open accessable data set for guided wave inspection techniques for carbon fibre reinforced polymers. Hence, data was recorded with our utmost care and expertise. A detailed description is attached to the data.
MANUFACTURING
The samples were produced according to the high standards of aerospace requirements.
QUALITY CONTROL
X-ray imaging and ultrasonic inspection assure the integrity of the samples. Material properties are provided.
WAVE PROPAGATION
Propagation behaviour of guided waves in the samples was recorded using a 3D laser Doppler vibrometer.
MEASURING
Guided waves signals were recorded for a large setup of frequencies and artificial defects in a controlled environment.
