  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.
