  text: "Woven fibre-reinforced polymers are used in a variety of application, especially
    where a low mass to stiffness ratio is required. Of paramount importance for the
    tailored mechanical properties these composite materials exhibit is the type and
    geometry of the fibre weave. Especially continuous fibre-reinforced thermoplastic
    composites are fabricated as laminates and subsequently exposed to forming processes
    which alter the geometry of the fibres unit cell and thus the local mechanical
    properties of the material. An approach utilising broadband ultrasonic waves is
    proposed to non-destructively determine the geometry of the unit cell of the weave.\r\n\r\nThe
    dispersive behaviour of woven fibre-reinforced sheets is described in accordance
    with the Flouquet-Bloch theorem as a phononic crystal. In order to develop a model
    for a description of these periodically structured waveguides, the smallest repeating
    unit of the wave is modelled with periodic boundary conditions. The resulting
    dispersion diagram exhibits similarities to that of a homogeneous plate, but additionally
    displays a periodicity in the wavenumber regime, which correspond with the size
    of the unit cell. Experimental studies of the dispersive behaviour of acoustic
    waves in woven fibre-reinforced samples also show a periodicity in the wavenumber
    regime, enabling a measurement procedure of the unit cell geometry."

  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>"
