  text: "<jats:title>Abstract</jats:title>\r\n               <jats:p>In this paper
    a measurement procedure to identify viscoelastic material parameters of plate-like
    samples using broadband ultrasonic waves is presented. Ultrasonic Lamb waves are
    excited via the thermoelastic effect using laser radiation and detected by a piezoelectric
    transducer. The resulting measurement data is transformed to yield information
    about multiple propagating Lamb waves as well as their attenuation. 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>"

  text: Acoustic waves in plates have proven a viable tool for testing and material
    characterisation purposes. 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.

  text: Die präzise Kenntnis der Eigenschaften verwendeter Materialien hat große Bedeutung
    für den Entwurf technischer Systeme aller Art, aber auch für die Überwachung solcher
    Systeme im Betrieb. 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. Im Vergleich mit den Ergebnissen mechanischer Zugversuche werden die
    Voraussetzungen und Einschränkungen, insbesondere durch die Annahme eines ideal-elastischen
    Materialmodells, diskutiert.

  text: Precise knowledge of material properties is a great concern in the design
    of technical systems, and in the monitoring of such systems during operation.
    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.

  text: An approach for the non-destructive characterisation of adhesive bonds using
    guided ultrasonic waves is presented. 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.

  text: "Waveguide-based methods can be used for the non-destructive determination
    of acoustic material parameters. 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."

  text: Die vollständige Beschreibung fluiddynamischer und akustischer Vorgänge setzt
    voraus, dass die Eigenschaften des Fluids hinlänglich bekannt sind.Während Fluidkenngrößen,
    wie etwa die Schallgeschwindigkeit oder die Scherviskosität, für viele Flüssigkeiten
    über weite Bereiche des thermodynamischen Zustandsraums bekannt sind, existieren
    für die Volumenviskosität nur eine geringe Anzahl Messdaten.In dieser Arbeit wird
    daher ein Messverfahren zur selektiven Bestimmung der Volumenviskosität von Flüssigkeiten,
    basierend auf der Absorption von Ultraschallwellen, entwickelt und realisiert.Schwerpunkte
    bilden dabei der simulationsgestützte Entwurf von Algorithmen zur Auswertung der
    Messsignale sowie die Analyse und Weiterentwicklung einer Messanordnung, basierend
    auf dem Puls-Echo-Verfahren. Neben der Absorption im Fluid treten dabei weitere
    Effekte (zum Beispiel Beugung oder unvollständige Reflexion) auf, die das akustische
    Signal schwächen oder anderweitig beeinflussen. Die Entwicklung von Verfahren
    zur Trennung dieser Effekte von der akustischen Absorption bildet daher einen
    weiteren Schwerpunkt dieser Arbeit.Abschließend wird die Volumenviskosität aus
    der gemessenen akustischen Absorption für unterschiedliche Fluide in verschiedenen
    thermodynamischen Zuständen unter Zuhilfenahme anderer bekannter Fluidkenngrößen
    bestimmt sowie eine Unsicherheitsbetrachtung durchgeführt.

  text: The prerequisite for a complete description of fluid dynamic and acoustic
    processes is that all properties of the fluid are known.While fluid parameters
    such as the speed of sound or the shear viscosity are known for many liquids over
    a wide range of thermodynamic states, only limited measurement data exist for
    the bulk viscosity.In this thesis, a measurement method for the selective determination
    of the bulk viscosity of liquids, based on the absorption of ultrasonic waves,
    is developed and implemented.The focus is on the simulation-driven design of algorithms
    for processing the measurement signals as well as the analysis and further development
    of a measurement set-up based on the pulse-echo method.In addition to absorption
    in the fluid, there are other effects (for example diffraction or incomplete reflection)
    that weaken or otherwise influence the acoustic signal.Therefore, the development
    of procedures to separate these effects from acoustic absorption is another focus
    of this work.The bulk viscosity is determined from the measured acoustic absorption
    for different fluids in different thermodynamic states. An uncertainty analysis
    of the measured quantities concludes this thesis.
