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."}],"status":"public","type":"journal_article","publication":"tm - Technisches Messen","title":"Inverse piezoelectric material parameter characterization using a single disc-shaped specimen","doi":"10.1515/teme-2020-0012","date_updated":"2026-01-05T07:53:10Z","author":[{"first_name":"Nadine","id":"23082","full_name":"Feldmann, Nadine","last_name":"Feldmann"},{"first_name":"Veronika","last_name":"Schulze","full_name":"Schulze, Veronika"},{"first_name":"Leander","full_name":"Claes, Leander","id":"11829","last_name":"Claes","orcid":"0000-0002-4393-268X"},{"last_name":"Jurgelucks","full_name":"Jurgelucks, Benjamin","first_name":"Benjamin"},{"first_name":"Andrea","last_name":"Walther","full_name":"Walther, Andrea"},{"first_name":"Bernd","last_name":"Henning","full_name":"Henning, Bernd","id":"213"}],"date_created":"2020-09-11T11:57:50Z","year":"2020","citation":{"short":"N.
