text: In this contribution, we address the estimation of the frequency-dependent
elastic parameters of polymers in the ultrasound range, which is formulated as
an inverse problem. This inverse problem is implemented as a nonlinear regression-type
optimization problem, in which the simulation signals are fitted to the measurement
signals. These signals consist of displacement responses in waveguides, focusing
on hollow cylindrical geometries to enhance the simulation efficiency. To accelerate
the optimization and reduce the number of model evaluations and wait times, we
propose two novel methods. First, we introduce an adaptation of the Levenberg–Marquardt
method derived from a geometrical interpretation of the least-squares optimization
problem. Second, we introduce an improved objective function based on the autocorrelated
envelopes of the measurement and simulation signals. Given that this study primarily
relies on simulation data to quantify optimization convergence, we aggregate the
expected ranges of realistic material parameters and derive their distributions
to ensure the reproducibility of optimizations with proper measurements. We demonstrate
the effectiveness of our objective function modification and step adaptation for
various materials with isotropic material symmetry by comparing them with the
Broyden–Fletcher–Goldfarb–Shanno method. In all cases, our method reduces the
total number of model evaluations, thereby shortening the time to identify the
material parameters.

text: "Abstract\r\n With the growing
demand for lightweight solutions to reduce emissions, especially in the transportation,
automotive and aerospace sectors, recyclable, continuous fiber-reinforced plastic
composite laminates with a thermoplastic matrix are of rising interest. To achieve
their maximum mechanical properties, the fiber-matrix adhesion (FMA) is critical.
In this work, continuous fiber-reinforced thermoplastic laminates (CFRTPL) with
a polypropylene (PP) matrix and twill woven glass fiber fabrics are produced by
film stacking. The films used contain different amounts of maleic-anhydride-grafted
PP (MA-g-PP) as a coupling agent to produce CFRTPL of different mechanical strengths.
To analyze the FMA, the CFRTPL are subjected to Charpy-impact and tensile tests.
Additionally, single fiber pull-out tests (SFPT) are conducted to further investigate
the effect of MA-g-PP on the FMA. The results of the SFPT show an improvement
in apparent interfacial shear strength (AIFSS) when the MA-g-PP content is increased,
which can be attributed to an increase in FMA. However, the research shows that
MA-g-PP has a low impact on the mechanical properties if the force is applied
parallel to the warp and weft threads during tensile testing and the results of
the Charpy-impact testing suffer from embrittlement of the matrix material. Subsequently,
the results of this study are compared to three-point flexural tests conducted
in a previous study. It can be concluded that tensile and impact tests are not
suited to investigate FMA on a macroscopic scale, while SFPT and flexural tests
provide a better alternative."

text: In diesem Forschungsprojekt wurde ein Messverfahren zur Bestimmung akustischer
Materialparameter von Polymeren im Ultraschallfrequenzbereich entwickelt. Das
Verfahrens sollte, die üblichen standardisierten Prüfmethoden erweitern, die bislang
primär im quasistatischen oder niederfrequenten Bereich eingesetzt wurden. Im
Gegensatz zu bestehenden Verfahren wie dem Zeitstandversuch oder der Dynamisch
Mechanischen Analyse (DMA) nach [DIN6721] sollte die neue Methode eine nicht-invasive
Charakterisierung der (visko-)elastischen Materialparameter im Frequenzbereich
von 0,75 MHz bis 2,5 MHz ermöglichen. Das entwickelte Ultraschallmesssystem arbeitet
nach dem Puls Echo-Prinzip und kann eine räumlich segmentierte, ringförmige Anregung
erzeugen. Die Bestimmung der frequenzabhängigen Materialparameter geschieht hierbei
über ein inverses Verfahren. Die Ergebnisse des Projekts zeigen, dass die Segmentierung
der Anregung, die Geometrie der Probe sowie das Puls-Echo-Messprinzip die Messergebnisse
sowie die Sensitivität gegenüber Scherparametern wesentlich beeinflussen. Im Rahmen
des Projektes wurde auch eine statistische Auswertung des Optimierungsverfahrens
hinsichtlich transversal-isotroper Materialsymmetrie mit Rayleigh-Dämpfung durchgeführt.
Die Ergebnisse zeigen, dass das entwickelte Verfahren gute Konvergenzeigenschaften
aufweist und sich durch verbesserte Robustheit auszeichnet.

text: This research project involved developing a measurement method to determine
the acoustic material parameters of polymers within the ultrasonic frequency range.
The aim of this method is to extend the range of standardised tests that operate
in the quasi-static or low-frequency range. In contrast to existing methods such
as the creep test or dynamic mechanical analysis according to [DIN6721], the developed
method is capable of non-invasive characterisation of the (visco-)elastic material
parameters in the frequency range of 0,75 MHz bis 2,5 MHz. The developed ultrasonic
measurement setup utilises the pulse-echo principle and can generate a spatially
segmented, ring-shaped excitation. The frequency-dependent material parameters
are determined using an inverse method. The final results of the project show
that the segmentation of the excitation, the geometry of the specimen and the
pulse-echo measurement principle have a significant influence on the measurement
results and the sensitivity to shear movements. As part of the project, a statistical
evaluation of the optimisation process was also carried out with regard to transversely
isotropic material symmetry with Rayleigh damping. The results show that the developed
process has good convergence properties and is characterised by improved robustness.

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: "Abstract\r\n Ultrasonic transmission
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."
