Pulsed laser radiation is used to thermoacoustically excite broadband ultrasonic waves in a multi-layered sample, consisting of a metal plate adhesively joined to a polymeric layer using synthetic resin. The resulting signals are received by a purpose-built piezoelectric transducer. Varying the distance between excitation and detection yields spatio-temporal measurement data, from which the dispersive properties of the propagating waves can be inferred using a two-dimensional Fourier transform, assuming the plates to act as coupled waveguides. Coupled multi-layered waveguides show an effect referred to as <jats:italic>mode repulsion</jats:italic>, where the distance between certain modes in the frequency-wavenumber domain is assumed to be a measure of coupling strength. Measurements at different stages of curing of the adhesive layer are performed and evaluated. A comparison of the results shows changes in the dispersive properties, namely an increased modal bandwidth for the fully cured sample as well as an increased modal distance."}],"type":"journal_article","date_created":"2021-11-11T09:38:20Z","user_id":"11829","doi":"10.1515/auto-2021-0089","department":[{"_id":"49"}],"publication":"at - Automatisierungstechnik","status":"public","project":[{"grant_number":"449607253","_id":"105","name":"Vermiedene Kreuzungen von Lamb-Wellenmoden in mehrlagigen Strukturen"}],"publication_status":"published","title":"An approach to adhesive bond characterisation using guided acoustic waves in multi-layered plates","language":[{"iso":"eng"}],"publication_identifier":{"issn":["2196-677X","0178-2312"]},"date_updated":"2022-01-17T13:06:47Z","year":"2021","page":"962-969","author":[{"full_name":"Zeipert, Henning","id":"32580","first_name":"Henning","last_name":"Zeipert"},{"orcid":"0000-0002-4393-268X","full_name":"Claes, Leander","id":"11829","first_name":"Leander","last_name":"Claes"},{"id":"29190","full_name":"Johannesmann, Sarah","first_name":"Sarah","last_name":"Johannesmann"},{"first_name":"Yevgeniya","last_name":"Lugovtsova","full_name":"Lugovtsova, Yevgeniya"},{"full_name":"Nicolai, Marcel","first_name":"Marcel","last_name":"Nicolai"},{"first_name":"Jens","last_name":"Prager","full_name":"Prager, Jens"},{"first_name":"Bernd","last_name":"Henning","full_name":"Henning, Bernd","id":"213"}],"quality_controlled":"1","_id":"27367","citation":{"chicago":"Zeipert, Henning, Leander Claes, Sarah Johannesmann, Yevgeniya Lugovtsova, Marcel Nicolai, Jens Prager, and Bernd Henning. “An Approach to Adhesive Bond Characterisation Using Guided Acoustic Waves in Multi-Layered Plates.” <i>At - Automatisierungstechnik</i>, 2021, 962–69. <a href=\"https://doi.org/10.1515/auto-2021-0089\">https://doi.org/10.1515/auto-2021-0089</a>.","bibtex":"@article{Zeipert_Claes_Johannesmann_Lugovtsova_Nicolai_Prager_Henning_2021, title={An approach to adhesive bond characterisation using guided acoustic waves in multi-layered plates}, DOI={<a href=\"https://doi.org/10.1515/auto-2021-0089\">10.1515/auto-2021-0089</a>}, journal={at - Automatisierungstechnik}, author={Zeipert, Henning and Claes, Leander and Johannesmann, Sarah and Lugovtsova, Yevgeniya and Nicolai, Marcel and Prager, Jens and Henning, Bernd}, year={2021}, pages={962–969} }","ama":"Zeipert H, Claes L, Johannesmann S, et al.
