Previous studies show that a full set of material parameters can be determined in an inverse procedure using a single disc-shaped specimen with an electrode structured for increased sensitivity with respect to all material parameters. However, in the case of high-power actuator applications, ring-shaped piezoelectric components are often employed, necessitating an adaptation of the previously developed method. The alteration in geometry introduces some advantages. Accordingly, there is no longer any requirement to modify the electrode structure in order to enhance sensitivity. The method to estimate the material parameters presented here consists of a total of three stages. An initial, approximate estimation of the material parameters is determined using analytical approximations for the resonance frequencies from the IEEE standard. These values are optimised in an inverse procedure that employs analytic expressions for the electrical impedance of piezoelectric rings as the forward model. Further refinement is achieved by using Finite Element (FE) simulations as the forward model again in an inverse procedure. The method is applied to electrical impedance measurement data, yielding material parameters for hard piezoelectric rings. The result shows a good agreement between the simulation and measurement results, indicating realistic material parameter values."}]},{"title":"Inverse procedure for measuring piezoelectric material parameters using a single multi-electrode sample","main_file_link":[{"open_access":"1","url":"https://jsss.copernicus.org/articles/12/163/2023/jsss-12-163-2023.pdf"}],"doi":"10.5194/jsss-12-163-2023","oa":"1","date_updated":"2026-01-05T07:57:13Z","author":[{"first_name":"Leander","last_name":"Claes","orcid":"0000-0002-4393-268X","full_name":"Claes, Leander","id":"11829"},{"first_name":"Nadine","last_name":"Feldmann","id":"23082","full_name":"Feldmann, Nadine"},{"first_name":"Veronika","full_name":"Schulze, Veronika","last_name":"Schulze"},{"first_name":"Lars","id":"24769","full_name":"Meihost, Lars","last_name":"Meihost"},{"full_name":"Kuhlmann, Henrik","last_name":"Kuhlmann","first_name":"Henrik"},{"last_name":"Jurgelucks","full_name":"Jurgelucks, Benjamin","first_name":"Benjamin"},{"first_name":"Andrea","full_name":"Walther, Andrea","last_name":"Walther"},{"first_name":"Bernd","last_name":"Henning","id":"213","full_name":"Henning, Bernd"}],"date_created":"2023-06-01T12:55:43Z","volume":12,"year":"2023","citation":{"ieee":"L.

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."}],"type":"journal_article","publication":"Engineering Reports","main_file_link":[{"open_access":"1","url":"https://onlinelibrary.wiley.com/doi/abs/10.1002/eng2.12573"}],"doi":"10.1002/eng2.12573","title":"An explicit symplectic approach to solving the wave equation in moving media","date_created":"2019-01-09T14:37:29Z","author":[{"first_name":"Venkatesh","id":"75069","full_name":"Inguva, Venkatesh","last_name":"Inguva"},{"last_name":"Feldmann","full_name":"Feldmann, Nadine","id":"23082","first_name":"Nadine"},{"first_name":"Leander","id":"11829","full_name":"Claes, Leander","last_name":"Claes","orcid":"0000-0002-4393-268X"},{"full_name":"Koturbash, Taras","last_name":"Koturbash","first_name":"Taras"},{"first_name":"Thomas","full_name":"Hahn-Jose, Thomas","last_name":"Hahn-Jose"},{"full_name":"Koutcherov, Vladimir","last_name":"Koutcherov","first_name":"Vladimir"},{"id":"665","full_name":"Kenig, Eugeny","last_name":"Kenig","first_name":"Eugeny"}],"oa":"1","date_updated":"2022-09-19T06:59:57Z","citation":{"chicago":"Inguva, Venkatesh, Nadine Feldmann, Leander Claes, Taras Koturbash, Thomas Hahn-Jose, Vladimir Koutcherov, and Eugeny Kenig. “An Explicit Symplectic Approach to Solving the Wave Equation in Moving Media.” <i>Engineering Reports</i>, 2022. <a href=\"https://doi.org/10.1002/eng2.12573\">https://doi.org/10.1002/eng2.12573</a>.","ieee":"V.

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>","lang":"eng"}],"date_created":"2022-04-12T11:00:22Z","publisher":"Walter de Gruyter GmbH","title":"Lamb wave based approach to the determination of acoustic material parameters","issue":"7 - 8","quality_controlled":"1","year":"2022"},{"user_id":"11829","department":[{"_id":"49"}],"project":[{"name":"ChaMP: Ein modellbasiertes Messverfahren zur Charakterisierung der frequenzabhängigen Materialeigenschaften von Piezokeramiken unter Verwendung eines einzelnen Probekörperindividuums","_id":"90"},{"_id":"245","name":"FOR 5208: Modellbasierte Bestimmung nichtlinearer Eigenschaften von Piezokeramiken für Leistungsschallanwendungen (NEPTUN)"}],"_id":"6553","language":[{"iso":"eng"}],"file_date_updated":"2022-03-28T14:21:06Z","ddc":["620"],"type":"conference","publication":"Fortschritte der Akustik - DAGA 2022","file":[{"relation":"main_file","success":1,"content_type":"application/pdf","access_level":"closed","file_id":"30666","file_name":"daga2022 cla.pdf","file_size":1143917,"creator":"leanderc","date_created":"2022-03-28T14:21:06Z","date_updated":"2022-03-28T14:21:06Z"}],"status":"public","author":[{"first_name":"Leander","full_name":"Claes, Leander","id":"11829","orcid":"0000-0002-4393-268X","last_name":"Claes"},{"first_name":"Nadine","last_name":"Feldmann","full_name":"Feldmann, Nadine","id":"23082"},{"first_name":"Veronika","last_name":"Schulze","full_name":"Schulze, Veronika"},{"full_name":"Jurgelucks, Benjamin","last_name":"Jurgelucks","first_name":"Benjamin"},{"first_name":"Andrea","last_name":"Walther","full_name":"Walther, Andrea"},{"full_name":"Henning, Bernd","id":"213","last_name":"Henning","first_name":"Bernd"}],"date_created":"2019-01-09T14:36:59Z","date_updated":"2026-01-05T07:52:51Z","conference":{"location":"Stuttgart","end_date":"2022-03-24","start_date":"2022-03-21","name":"DAGA 2022 - 48.

One of these methods is based on transmission measurements of cylindrical polymeric specimens. Here, the experimental setup consists of two transducers, which excite and receive the waveguide modes at the faces of the cylinder. The measurement, as well as a forward model, are used to determine material parameters of the polymeric specimen in an inverse approach.\r\n1-3 piezoelectric composites are used as an active element because they can be approximated by a thickness vibration only. This allows an easy identification of Mason model parameters to characterise the transducers’ vibration behaviour. \r\nHowever, sensitivity analysis shows a high uncertainty in the determination of the mechanical shear parameters due to the uniform excitation. To increase the sensitivity to these shear motions, arbitrary excitations were investigated by means of numerical simulation. \r\nIn order to be able to realise the determined optimal excitation, new transducer prototypes were designed. By subdividing the electrodes of the active element, for example, ring-shaped excitation is feasible. Furthermore, it can be shown that modelling these transducers with a one-dimensional Mason model is sufficient.","lang":"eng"}],"file":[{"content_type":"application/octet-stream","success":1,"relation":"main_file","date_updated":"2021-10-04T07:49:28Z","date_created":"2021-10-04T07:49:28Z","creator":"dmitrij","file_size":906618,"file_name":"daga","file_id":"25268","access_level":"closed"}],"publisher":"Deutsche Gesellschaft für Akustik e.V.

Dabei ist vor allem die Wahl der Materialparameter der verwendeten Materialien wichtig für ein realitätsnahes Simulationsergebnis. Bei Schallwandlern werden häufig Piezokeramiken als aktive Elemente genutzt, welche sich durch eine Verkopplung mechanischer und elektrischer Eigenschaften auszeichnen. Zur Bestimmung ihrer Materialparameter stellt der IEEE Standard on Piezoelectricity ein standardisiertes Verfahren dar. Dazu sind fünf Impedanzmessungen an vier unterschiedlich gefertigten Probekörpergeometrien notwendig. Da an jedem einzelnen Probekörper nur eine Untermenge aller notwendigen Materialparameter bestimmt werden kann, werden diese dann zu einem kompletten Materialparametersatz zusammengefügt. Aufgrund der unterschiedlichen Prozessbedingungen, bei denen die jeweiligen Probekörper hergestellt werden, ist dieser Materialparametersatz jedoch inkonsistent und kann nie das Verhalten einer einzelnen Probe beschreiben. Daher wird in der vorliegenden Arbeit ein Messverfahren entwickelt, mit dem es möglich ist, alle relevanten Materialparameter unter besonderer Berücksichtigung von Dämpfung an einem einzelnen Probekörper allein durch Impedanzmessungen zu bestimmen. Als Probekörper wird dazu eine in der Anwendung häufig verwendete Scheibengeometrie verwendet. Um eine hinreichend hohe Sensitivität auf alle Materialparameter zu gewährleisten, wird diese mit einer optimierten Elektrodentopologie gefertigt. Da in diesem Fall keine analytische Betrachtung mehr möglich ist, wird das Messverfahren durch einen inversen Ansatz realisiert.","lang":"ger"},{"text":"Design processes of ultrasonic transducers become increasingly simulation-driven due to rising computational capabilities. Therewithin, the choice of the material parameters for modelling the materials used is particularly important for a realistic simulation result. Piezoceramics, which couple mechanic and electrical properties, are often used as active elements in ultrasonic transducers.The IEEE Standard on Piezoelectricity is a standardised procedure for determining these parameters that requires five impedance measurements on four piezocermics of different geometry. Since only a subset of all necessary material parameters can be determined for each individual specimen, these are then combined to form a complete set of material parameters. Due to different processing conditions for each specimen, this set of material parameters is inconsistent and cannot describe the behaviour of a single specimen appropriately. Therefore, in the present thesis, a method is developed with enables the determination of all relevant material parameters including damping on a single piezocermic by means of electrical impedance measurements alone. A piezoelectric ceramic with disc-shaped geometry, which is frequently used in applications, is used as a specimen.In order to ensure a sufficiently high sensitivity to all material parameters, it is manufactured with an optimised electrode topology. Because in this case analytical solutions, which relate the measurement quantities to the material parameters, do not exist, the measurement method is implemented using an inverse approach.","lang":"eng"}],"type":"dissertation"},{"page":"294 - 302","intvolume":"        88","citation":{"ama":"Feldmann N, Schulze V, Claes L, et al.

A newly developed procedure can be used to identify the behaviour of piezoceramic discs over a wide frequency range using a single specimen via fitting simulated and measured impedances by optimising the underlying material parameters. Since there is no generally accepted damping model for piezoelectric ceramics, several mechanical damping models are examined for the material identification. Three models have been chosen and their ability to replicate the measured impedances is evaluated. On the one hand, the common Rayleigh model is considered as a reference. On the other hand, a Zener model and a model using complex constants are extended to model the transversely isotropic material. As the Rayleigh model is only valid for a limited frequency range, it fails to model the broadband behaviour of the material. The model using complex constants leads to the best fit over a wide frequency range while at the same time only adding three additional parameters for modelling damping. Thus, damping can be assumed approximately frequency-independent in piezoceramics.","lang":"eng"}],"publication":"tm - Technisches Messen","language":[{"iso":"eng"}]},{"author":[{"first_name":"Leander","id":"11829","full_name":"Claes, Leander","last_name":"Claes","orcid":"0000-0002-4393-268X"},{"first_name":"Nadine","full_name":"Feldmann, Nadine","id":"23082","last_name":"Feldmann"},{"last_name":"Jurgelucks","full_name":"Jurgelucks, Benjamin","first_name":"Benjamin"},{"first_name":"Veronika","last_name":"Schulze","full_name":"Schulze, Veronika"},{"last_name":"Schmidt","full_name":"Schmidt, Stephan","first_name":"Stephan"},{"full_name":"Walther, Andrea","last_name":"Walther","first_name":"Andrea"},{"last_name":"Henning","full_name":"Henning, Bernd","id":"213","first_name":"Bernd"}],"date_created":"2021-05-06T16:25:42Z","date_updated":"2026-01-05T07:54:28Z","doi":"10.5162/SMSI2021/A10.1","conference":{"location":"Nürnberg","name":"Sensor and Measurement Science International"},"title":"Optimised Multi-Electrode Topology for Piezoelectric Material Characterisation","publication_identifier":{"unknown":["978-3-9819376-4-0"]},"page":"237-238","citation":{"ama":"Claes L, Feldmann N, Jurgelucks B, et al.

Exact results can only be achieved when a single specimen is used in the identification process, which typically is prone to the problem of low sensitivities to certain material parameters and thus high uncertainties. Therefore, a custom electrode topology for increased sensitivity is proposed for a piezoceramic disc. The thereupon conducted measurements of the electric impedance can be used as a starting point for an inverse approach where an equivalent simulation model is used to identify fitting material parameters. An optimisation strategy based on a preliminary sensitivity analysis is presented that leads to a good agreement between measurement and simulation. Furthermore, the proposed measurement procedure is able to evaluate the quality of the simulation model. Hence, different frequency-dependent damping models are presented and evaluated."}],"type":"journal_article","publication":"tm - Technisches Messen"}]
