Keynote [11:40–12:40]

Chairs: Krzysztof Dragan, Łukasz Ambroziński

11:40 - 12:40	Ultrasound Meets Composites: Imaging Damage, Structure and Stiffness
	Dr. Mathias Kersemans @ Ghent University, Ghent, Belgium.
	Ultrasonic inspection remains the gold standard for non-destructive evaluation of fiber-reinforced polymers in the aerospace industry. However, the full potential of ultrasound for characterizing these complex materials is still far from fully realized. In this talk, we present recent advances in ultrasonic inspection of fiber-reinforced polymers, highlighting how ultrasound data can be leveraged to enable novel imaging modalities. Specifically, we demonstrate: (1) Damage imaging, using statistical time–energy analysis to resolve complex and distributed defects; (2) Structural imaging, employing a tomographic approach to reconstruct the three-dimensional multilayered fiber architecture; (3) Functional imaging, based on inverse methods to identify the anisotropic viscoelastic stiffness tensor. For each imaging modality, the underlying principles are briefly introduced and supported by experimental demonstrations, illustrating the potential of ultrasound as a comprehensive tool for advanced material characterization.

Keynote [11:40–12:40]

Chairs: Krzysztof Dragan, Łukasz Ambroziński

11:40 - 12:40	Studying Crystal Acoustics Using Lasers – Recent Progress.
	Prof. Hanuś Seiner @ Institute of Thermomechanics of the CAS, Praha, Czech Republic.
	Laser-ultrasonic (LU) methods are experimental techniques utilizing laser beams for generation and detection of ultrasonic waves and vibrations. These methods, thus, enable characterization of mechanical properties of solids without mechanically touching them. During the past two decades, several unique LU experimental arrangements have been developed at the Institute of Thermomechanics, among which LU measurements of anisotropic acoustic properties of single crystals have achieved particular recognition. These approaches allowed us to contribute to developing new alloys for applications ranging from bone implants, over flexible electronics, to space research. The lecture will present two our recent advancements in this direction: reaching Weyl’s asymptotic behavior in resonant ultrasound spectroscopy, and detecting ultra-transient oscillations in transient-grating experiments. Both these advancements have close relations to mathematical foundations of elastodynamics. In the former, we observe statistics of several hundreds of experimentally obtained eigenvalues and eigenvectors of an operator representing a freely vibrating single crystal; in the latter, we obtain a direct visualization of Green’s function for a hyperbolic differential operator representing elastodynamics of a free surface.
