    measurements can be used for material characterization, as the propagation time
    of sound waves and thus their velocity depends on the elastic material parameters.
    Measurement results for the elastic material parameters are acquired non-destructively
    using ultrasonic transmission measurements of hollow cylindrical polymer specimens.
    To determine the material parameters, an inverse approach is used comparing measurements
    with simulated data. Previous studies show that the procedure exhibits low sensitivity
    with respect to the shear parameters of the material. In order to increase the
    sensitivity, we propose to apply a spatially annular excitation on the base of
    the specimen. As a measure to analyse the sensitivities with respect to all parameters
    and their linear independence, we observe the volume of the parallelotope of the
    sensitivity vectors. Here, a scaled boundary finite element formulation of wave
    propagation in the specimen is expanded to yield derivative information directly,
    and a sensitivity analysis can be carried out efficiently. Finally, the results
    of this sensitivity analysis with regard to the annular excitation are also applied
    to the measurement setup.</jats:p>"

  text: The degree of crosslinking in unidirectional prepreg materials was investigated
    using differential scanning calorimetry to assess their curing behavior and thermal
    characteristics. To complement these measurements with a non-destructive, in-situ
    method, the propagation properties of guided acoustic waves in cured carbon fibre-reinforced
    epoxy plates were analysed. Correlations between the degree of crosslinking and
    acoustically determined mechanical properties were drawn to enable a future non-destructive
    evaluation approach.

  text: In this contribution, we present an efficient approach for the transient and
    time-causal modeling of guided waves in viscoelastic cylindrical waveguides in
    the context of ultrasonic material characterization. We use the scaled boundary
    finite element method (SBFEM) for efficient computation of the phase velocity
    dispersion. Regarding the viscoelastic behavior of the materials under consideration,
    we propose a decomposition approach that considers the real-valued frequency dependence
    of the (visco-)elastic moduli and, separately, of their attenuation. The modal
    expansion approach is utilized to take the transmitting and receiving transducers
    into account and to propagate the excited waveguide modes through a waveguide
    of finite length. The effectiveness of the proposed simulation model is shown
    by comparison with a standard transient FEM simulation as well as simulation results
    based on the exact solution of the complex-valued viscoelastic guided wave problem.
    Two material models are discussed, namely the fractional Zener model and the anti-Zener
    model; we re-interpret the latter in terms of the Rayleigh damping model. Measurements
    are taken on a polypropylene sample and the proposed transient simulation model
    is used for inverse material characterization. The extracted material properties
    may then be used in computer-aided design of ultrasonic systems.
