    <title language="eng">Nondestructive defect characterization using full-frame spatially structured super resolution laser thermography</title>
    <abstract language="deu">Die laserbasierte aktive thermografische Prüfung als berührungslose Methode der zerstörungsfreien Werkstoffprüfung (NDT) basiert auf der aktiven Erwärmung des Testobjekts (OuT) und Messung des resultierenden Temperaturanstiegs mit einer Infrarotkamera. Dadurch bedingt können systematische Abweichungen vom vorhergesagten Erwärmungsverhalten Aufschluss über dessen innere Struktur geben. Jedoch ist das Auflösungsvermögen für innenliegende Defekte durch die diffusive Natur der Wärmeleitung in Festkörpern begrenzt. Thermografische Super-Resolution (SR)-Methoden zielen darauf ab, diese Limitation durch die Kombination mehrerer Messungen mit jeweils unterschiedlicher strukturierter Erwärmung und mathematischer Optimierungsmethoden zu überwinden.&#13;
Zur Rekonstruktion innerer Defekte mithilfe thermografischer SR-Rekonstruktionsmethodik wird für die Gesamtheit mehrerer Messungen ein schlecht gestelltes und stark regularisiertes inverses mathematisches Problem gelöst, was in einer dünnbesetzten Karte der internen Defektstruktur des OuTs resultiert.&#13;
&#13;
Der vorliegende Vortrag gibt einen Überblick über die geleisteten Arbeiten in diesem Gebiet im Rahmen der hier mit dem Wissenschaftspreis der DGZfP 2024 prämierten Arbeit.</abstract>

    <title language="eng">Automated non-destructive internal corrosion detection on radioactive drums (ZIKA)</title>
    <abstract language="eng">The aim of the ZIKA research project, funded by the BMBF funding program FORKA (FKZ:15S9446 A-C), is the automated detection of internal corrosion of radioactive drums using non-destructive testing (NDT). The newly gained findings will be combined with research results from the previous project EMOS (FKZ:15S9420), which dealt with the external damage of drums. Using NDT, internal corrosion and possible internal sources of damage can be identified before they become a safety-relevant issue. However, if internally sourced damages can be seen externally, the integrity of the damaged drum is no longer guaranteed, which has significant consequences. Therefore, early detection before integrity failure is of particular importance for interim storage facilities with low- and medium-level radioactive waste drums.</abstract>

    <title language="eng">Fatigue damage detection using Lock-In Thermography</title>
    <abstract language="eng">Early detection of fatigue cracks and accurate measurements of the crack growth play an important role in the maintenance and repair strategies of steel and composite structures exposed to cyclic loads during their service life. Commonly used non-destructive techniques such as strain gauges, clip gauges, ultrasound, etc. used for detection and monitoring of fatigue damage are contact-based and perform local measurements. In addition, complex full-field techniques are commonly investigated, such as digital image correlation (DIC) and infrared thermography (IRT). In this work, a specific implementation of IRT, called lock-in IRT, is implemented for fatigue damage detection. This technique evaluates the thermal stress response of test specimens, specifically focusing or “locking-in” on the frequency of applied cyclic loads. Three different test scenarios are presented.&#13;
First, a section of a wind turbine rotor blade made of a glass fibre reinforced plastic (GFRP) shell structure under cyclic load was examined with Lock-In IRT along with DIC. The primary advantage of Lock-In IRT in this test setup was that it required no sample preparation, as compared to the painting and speckle pattern required for DIC. In the frequency domain, specifically the frequency of applied cyclic load, it was possible to extract local directional inhomogeneous loading within the shell structure due to progressive damage, confirmed with the deformation obtained from DIC results. &#13;
Second, thick welded specimens made of structural steel S355 were subjected to multiple NDT methods such as strain gauges, crack luminescence penetration (developed specifically at BAM), ultrasound, and IRT, with the aim of investigating the ability of each technique to detect fatigue damage initiation as early as possible in the total fatigue life of the specimen. Amongst the range of implemented techniques, Lock-In IRT provided the first indication of fatigue crack initiation at the weld toe of the specimens. This was validated with the other techniques as well as fractography.&#13;
Third, steel S355 specimens used to manufacture offshore wind turbine monopiles were tested. The specimens were extracted from a plate that was submerged in a marine environment, resulting in a corroded surface with corrosion pits. These specimens were subjected to cyclic tensile loads without removing the corrosion pits. The fatigue tests were monitored using IRT in a special full-field capturing setup that enables both sides of the specimen to be examined with one IRT camera. This allowed the entire pitted surface to be monitored for fatigue damage initiation at the same time. With the implementation of Lock In IRT, the surface stress distribution could be captured (the stress concentration at the pits), and fatigue crack initiation could be detected and linked with specific corrosion pits.</abstract>

    <title language="deu">Verbesserung der Kreislaufwirtschaft im Bauwesen durch Bauwerksdiagnose: Ein Einblick in das Projekt REINCARNATE</title>
    <abstract language="deu">Das EU-finanzierte Projekt REINCARNATE, im Rahmen des Horizont Europa Programms, setzt neue Maßstäbe in der Kreislaufwirtschaft des Bauwesens durch den Einsatz fortschrittlicher Bauwerksdiagnose-Tools. Diese Werkzeuge, insbesondere die Zerstörungsfreie Prüfung (ZfP), spielen eine zentrale Rolle bei der Förderung der Zirkularität in der Baubranche. Die ZfP ermöglicht es, die Qualität und Eignung von Baumaterialien präzise zu bestimmen, ohne diese zu beschädigen. Dies ist entscheidend für die Wiederverwendung und das Recycling von Baustoffen und trägt wesentlich zur Reduzierung des Bauabfalls bei. Durch die Integration dieser Technologie in die Planungs- und Entwurfsphase können Architekten und Ingenieure aktiv einen nachhaltigeren Bauprozess fördern. REINCARNATE verbindet diese Diagnosemethoden mit digitalen Innovationen wie der Technologie des digitalen Zwillings und KI-gesteuerten Lösungen. Diese Kombination ermöglicht eine noch genauere und effizientere Bewertung und Nutzung von Baustoffen, was die Wiederverwendbarkeit und das Recycling verbessert. Im Rahmen des Projekts werden elf Demonstrationsprojekte in ganz Europa umgesetzt, die die praktische Anwendung dieser Technologien zeigen. Diese Projekte demonstrieren, wie ZfP und digitale Werkzeuge zusammenwirken, um Materialien, die traditionell als Abfall angesehen werden, in wertvolle Ressourcen umzuwandeln. Das Ziel von REINCARNATE ist eine 80-prozentige Verringerung der Bauabfälle und eine 70-prozentige Reduzierung des CO2-Fußabdrucks. Mit diesem Beitrag demonstrieren wir eine klare, umsetzbare Anleitung für die Bauindustrie, wie Innovationen in die Praxis umgesetzt werden können. Wir präsentieren greifbare Strategien zur Implementierung nachhaltiger, zirkulärer Praktiken im Bauwesen und markiert einen Wendepunkt in Richtung einer nachhaltigeren Bauindustrie.</abstract>

    <title language="eng">Reincarnate: Shaping a sustainable future in construction through digital innovation</title>
    <abstract language="eng">We introduce the REINCARNATE project, funded by the European Union's Horizon Europe program, to boost circularity by merging digital innovations with practical applications and a focus on material reuse. The heart of REINCARNATE is the Circular Potential Information Model (CP-IM), a digital platform designed to assess and enhance the recyclability of construction materials, construction products, and buildings. The CP-IM integrates advanced technologies such as digital twins, AI, and robotics to revolutionize the handling of construction waste, turning it into valuable resources and cutting the environmental footprint of the sector. Among its features are digital tracing, material durability predictions, and CO2 reduction materials design. These are showcased in eleven European demonstration projects, highlighting the practical benefits of these technologies in reducing construction waste and CO2 emissions by up to 80% and 70% respectively. REINCARNATE aims to marry innovation with real-world application, providing the construction industry with strategies for sustainable and circular practices.</abstract>

    <title language="eng">Pulse compression for air-coupled ferroelectret and thermoacoustic transducers</title>
    <abstract language="eng">The main advantage of air-coupled ultrasonic testing is the absence of a liquid couplant, which can damage some materials. However, most air-coupled testing scenarios have the challenge of low signals and a signal-to-noise ratio (SNR) several orders of magnitude lower than with couplant-assisted techniques. Since this challenge of small SNR also exists in radar technology, the pulse compression used there was adapted and applied to the physical conditions of air-coupled ultrasonic testing. This paper presents ultrasonic transmission measurements on a carbon-fibre-reinforced polymer plate using two experimental setups: 1) a thermoacoustic transmitter and an optical microphone and 2) a pair of ferroelectret transducers as transmitter and receiver. Thermoacoustic transmitters convert electrical energy to heat, which causes the air to expand thus producing acoustic waves. The optical microphone is based on a Fabry-Perot interferometer. Ferroelectrets are charged cellular polymers, having piezoelectric properties and excellent acoustic matching to air. Both thermoacoustic transmitters and ferroelectrets are non-linear regarding the relationship between the excited sound pressure and the excitation voltage. Due to these physical boundary conditions, unipolar coding was used to modulate the excitation signals. Various codes were tested, and parameters of the excitation pulses were varied to find the optimal combination for each experimental setup. The application of pulse compression to the combination of thermoacoustic transmitter and optical microphone increased the signal-to-noise ratio by up to 16 dB and for the ferroelectret transducers by up to 23 dB.</abstract>
