A simple operator split of this second order wave equation into two coupled first order equations is performed, allowing these split equations to be solved symplectically. Orders of symplectic time integration ranging from first to fourth along with orders of spatial derivatives ranging from second to sixth are explored. The case of cylindrical acoustic spreading in air under a constant velocity in a 2D square structured domain is considered. The variation of the computed time-of-flight, frequency, and wave length are studied with varying grid resolution and the deviations from the analytical solutions are determined. It was found that symplectic time integration interferes with finite difference spatial derivatives higher than second order causing unexpected results. This is actually beneficial for unstructured finite volume tools like OpenFOAM where second order spatial operators are the state-of-the art. Cylindrical acoustic spreading is simulated on an unstructured 2D triangle mesh showing that symplectic time integration is not limited to the spatial discretization paradigm and overcomes the numerical diffusion arising with the in-built numerical methods which hinder wave propagation."}],"publication":"Engineering Reports","citation":{"apa":"Inguva, V., Feldmann, N., Claes, L., Koturbash, T., Hahn-Jose, T., Koutcherov, V., &#38; Kenig, E.

These results are compared to simulation results in an inverse procedure to identify the parameters of an elastic and a viscoelastic material model.</jats:p>"}],"language":[{"iso":"eng"}],"doi":"10.1515/teme-2021-0134","author":[{"id":"29190","first_name":"Sarah","last_name":"Johannesmann","full_name":"Johannesmann, Sarah"},{"id":"11829","full_name":"Claes, Leander","last_name":"Claes","orcid":"0000-0002-4393-268X","first_name":"Leander"},{"id":"23082","last_name":"Feldmann","first_name":"Nadine","full_name":"Feldmann, Nadine"},{"last_name":"Zeipert","first_name":"Henning","full_name":"Zeipert, Henning","id":"32580"},{"id":"213","first_name":"Bernd","last_name":"Henning","full_name":"Henning, Bernd"}],"publication_identifier":{"issn":["2196-7113","0171-8096"]},"year":"2022","title":"Lamb wave based approach to the determination of acoustic material parameters","intvolume":"        89","date_updated":"2023-10-23T06:56:20Z","publication_status":"published","citation":{"ieee":"S.

There are a multitude of options for excitation and detection of theses waves, such as optical and piezoelectric systems. While optical systems, with thermoelastic excitation and interferometric detection, have the benefit of being contactless, they usually require rather complex and expensive experimental setups. Piezoelectric systems are more easily realised but require direct contact with the specimen and usually have a limited bandwidth, especially in case of piezoelectric excitation. In this work, the authors compare the properties of piezoelectric and optical detection methods for broad-band acoustic signals. The shape (e. g. the displacement) of a propagating plate wave is given by its frequency and wave number, allowing to investigate correlations between mode shapes and received signal strengths. This is aided by evaluations in normalised frequency and wavenumber space, facilitating comparisons of different specimens. Further, the authors explore possibilities to utilise the specific properties of the detection methods to determine acoustic material parameters.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1515/teme-2020-0098","alternative_title":["Untersuchung von Eigenheiten piezoelektrischer Detektionsmethoden für akustische Plattenwellen zur Materialcharakterisierung"],"year":"2021","title":"Investigating peculiarities of piezoelectric detection methods for acoustic plate waves in material characterisation applications","author":[{"id":"11829","first_name":"Leander","orcid":"0000-0002-4393-268X","last_name":"Claes","full_name":"Claes, Leander"},{"last_name":"Schmiegel","first_name":"Hanna","full_name":"Schmiegel, Hanna"},{"last_name":"Grünsteidl","first_name":"Clemens","full_name":"Grünsteidl, Clemens"},{"id":"29190","first_name":"Sarah","last_name":"Johannesmann","full_name":"Johannesmann, Sarah"},{"first_name":"Manuel","last_name":"Webersen","orcid":"0000-0001-6411-4232","full_name":"Webersen, Manuel","id":"11289"},{"full_name":"Henning, Bernd","last_name":"Henning","first_name":"Bernd","id":"213"}],"publication_identifier":{"issn":["2196-7113","0171-8096"]},"publication_status":"published","date_updated":"2022-01-06T06:54:44Z","intvolume":"        88"},{"type":"journal_article","department":[{"_id":"49"}],"date_created":"2021-01-26T13:52:47Z","project":[{"_id":"89","grant_number":"409779252","name":"Vollständige Bestimmung der akustischen Materialparameter von Polymeren"}],"publication":"PAMM","citation":{"mla":"Itner, Dominik, et al. “Simulation of Guided Waves in Cylinders Subject to Arbitrary Boundary Conditions for Applications in Material Characterization.” <i>PAMM</i>, 2021, doi:<a href=\"https://doi.org/10.1002/pamm.202000232\">10.1002/pamm.202000232</a>.","bibtex":"@article{Itner_Gravenkamp_Dreiling_Feldmann_Henning_2021, title={Simulation of guided waves in cylinders subject to arbitrary boundary conditions for applications in material characterization}, DOI={<a href=\"https://doi.org/10.1002/pamm.202000232\">10.1002/pamm.202000232</a>}, journal={PAMM}, author={Itner, Dominik and Gravenkamp, Hauke and Dreiling, Dmitrij and Feldmann, Nadine and Henning, Bernd}, year={2021} }","ama":"Itner D, Gravenkamp H, Dreiling D, Feldmann N, Henning B.

Für verschiedene physikalische Eigenschaften, Betriebsbedingungen und Materialklassen werden daher geeignete messtechnische Verfahren zur Materialcharakterisierung benötigt. In der vorliegenden Arbeit wird ein Verfahren zur ultraschallbasierten Charakterisierung der mechanischen Eigenschaften von homogenen und faserverstärkten thermoplastischen Polymeren unter Berücksichtigung der Richtungsabhängigkeit vorgestellt. Plattenförmige Probekörper werden dazu mittels Laser-Pulsen hoher Energie breitbandig angeregt und die resultierenden akustischen Lamb-Wellen aufgezeichnet. Auf Basis der dispersiven Eigenschaften der detektierten Wellenleitermoden werden in einem inversen Verfahren die Parameter eines linear-elastischen Materialmodells identifiziert. Darüber hinaus wird ein Verfahren zur vollständigen Charakterisierung der Richtungsabhängigkeit in orthotropen Materialien wie Faserverbundwerkstoffen unter Verwendung eines zweidimensionalen Simulationsmodells vorgestellt. Das Messverfahren wird anhand einer Untersuchungsreihe an künstlich gealterten Polymer- und Faserverbundwerkstoffen verifiziert und die Übertragbarkeit der Ergebnisse auf den quasistatischen Fall betrachtet.

Therefore, metrological processes are required for materials characterisation with respect to specific physical properties, operational conditions and classes of materials. In the work presented herein, a measurement procedure for the ultrasonic characterization of mechanical properties of homogeneous and fiber-reinforced thermoplastic polymer materials is presented, considering the different degrees of anisotropy. For this, acoustic Lamb waves are excited in a plate-shaped specimen using high-energy laser pulses, and then recorded.Based on the dispersive characteristics of the detected waveguide modes, an inverse procedure is applied to identify the parameters of a linear-elastic material model. Further, a procedure for completely characterising the orthotropy of materials like fiber-reinforced composites using a two-dimensional simulation model is presented. The measurement procedure is verified by examining artificially aged homogeneous polymers and composites, also considering the applicability of results to the quasistatic case. Comparing to the results of corresponding mechanical tensile tests, preconditions and limitations of the procedure are discussed, specifically regarding the assumption of an ideal-elastic material model."}],"language":[{"iso":"ger"}],"_id":"21183","publisher":"Universitätsbibliothek Paderborn","doi":"10.17619/UNIPB/1-1088","user_id":"11289","title":"Zerstörungsfreie Charakterisierung der elastischen Materialeigenschaften thermoplastischer Polymerwerkstoffe mittels Ultraschall","status":"public","year":"2021","author":[{"full_name":"Webersen, Manuel","orcid":"0000-0001-6411-4232","first_name":"Manuel","last_name":"Webersen","id":"11289"}],"date_updated":"2022-01-06T06:54:49Z","publication_status":"published"},{"project":[{"_id":"89","grant_number":"409779252","name":"Vollständige Bestimmung der akustischen Materialparameter von Polymeren"}],"citation":{"apa":"Itner, D., Gravenkamp, H., Dreiling, D., Feldmann, N., &#38; Henning, B.
