BAM8.3 - Thermographic Methods

The structural integrity of wind turbine rotor blades is one of the biggest challenges facing the wind industry. This issue is being tackled head-on in a new research project called ReliaBlade2 that BAM, together with German industries and research institutes, launched in 2025. ReliaBlade2 aims to improve the current blade testing procedures and thus not only increase the reliability and structural integrity of the new designs of wind turbine blades but also reduce the operating and maintenance costs of wind turbines. The project will run for four years and is a collaboration between Bundesanstalt für Materialforschung und -prüfung and Fraunhofer-Institut für Windenergiesysteme, ENERCON, Nordex Group, TPI Composites, Inc., ForWind - Center for Wind Energy Research and RE Technologies GmbH– a one of its kind cooperation between blade designers, manufacturers and researchers. 🚀 The role of BAM8.3 - Thermographic Methods 🚀 is to implement infrared thermographic inspection, a technique requiring no contact with the examined surface, during the mechanical testing of both coupon- and full-scale blades and blade material. This will help in detecting weak spots over a large inspection area otherwise not possible or very expensive with other conventional sensors. Based on Thermoelastic stress analysis, the thermography data will contribute to the development of new fatigue models that will inform the new blade designs. This endeavor will primarily be led by Ivana Lapsanska, Michael Stamm, and Rainer Krankenhagen. They will be supported by Somsubhro Chaudhuri in mechanical testing and Patrick Grzywok in robotics.

🎉 Welcome aboard, Dimitrij Schulz! 🎉 We’re excited to introduce Dimitrij Schulz as a new student assistant at BAM8.3 - Thermographic Methods.📑 📚 Dimitrij is currently pursuing his master’s degree in Computer Science at Technische Universität Berlin, where he also earned his Bachelor’s degree with a focus on machine learning. Now, he’s bringing his skills and enthusiasm to our team! 🌐 At Bundesanstalt für Materialforschung und -prüfung, Dimitrij is working closely with Somsubhro Chaudhuri, Ivana Lapsanska and Michael Stamm to enhance our wind turbine blade field inspection tools. His focus involves integrating a weather station into our inspection setup to capture local weather data and improving how we interpret thermal data using COMSOL simulations. 💡 Additionally, he’s contributing to the refinement of our post-processing codes for analysing thermography data from cyclically loaded mechanical tests. This work is key to implementing Thermoelastic Stress Analysis (TSA), helping us better characterize material behaviour under stress loading such as metallic components or rotor blade sections. Outside of his studies and work, Dimitrij enjoys watching documentaries about history and staying active through various sports. 🙌 If you’re interested in student assistant roles or collaborative projects, please reach out! #NewTeamMember #InfraredThermography #StudentAssistant #BAMResearch #MaterialTesting

Heute besuchte uns bei der Bundesanstalt für Materialforschung und -prüfung (BAM) eine interessierte Gruppe von jungen Physik-Studierenden im Rahmen des Laborbesichtigungsprogramm "Ein Tag vor Ort" initiiert vom Arbeitskreis Industrie und Wirtschaft der Deutsche Physikalische Gesellschaft e. V. (DPG).   Auf dem Programm standen die vielfältigen Möglichkeiten der Zerstörungsfreien Prüfung (https://lnkd.in/eeJMT6Sf ) angefangen bei Ultraschall- und Thermografieverfahren mit Robotern über dronenbasierte Gassensorik und dem Einsatz künstlicher Intelligenz bis hin zur Röntgen-Computertomographie (XCT) und Thermografie an Windkraftanlagen.   Eine spannende Gelegenheit, typische Arbeitsplätze von Physikerinnen und Physikern in einem sowohl wissenschaftlich geprägten als auch industriell orientierten Umfeld kennenlernen können!   Wir danken für das Interesse und die spannenden Fragen und ein großes Dankeschön an alle aus dem BAM-Team, die zu dieser erfolgreichen Veranstaltung beigetragen haben (u. a. BAM8.3 - Thermographic Methods, Nicolas P. Winkler, Mathias Ziegler, Giovanni Bruno, Philipp Hirsch, Tobias Fritsch, Ramanan Sridaran Venkat uvm.)!     Today, an interested group of young physics students visited us at Bundesanstalt für Materialforschung und -prüfung (BAM) as part of the ‘Ein Tag vor Ort’ laboratory tour programme initiated by the Arbeitskreis Industrie und Wirtschaft of the Deutsche Physikalische Gesellschaft e. V. (DPG) (German Physical Society).   The programme included a wide range of non-destructive testing options (https://lnkd.in/eHvCBeeC ), starting with ultrasonic and thermographic methods using robots, drone-based gas sensors and the use of artificial intelligence, and ending with X-ray computed tomography (XCT ) and thermography on wind turbines.   It was an exciting opportunity to get to know typical workplaces of physicists in both a scientific and industrial environment!   We thank you for the interest and the exciting questions and a big thank you to everyone from the BAM team who contributed to this successful event (among others BAM8.3 - Thermographic Methods, Nicolas P.

👨🔬New Project Leader of laser-based thermography project!  We are excited to share that our colleague Philipp Hirsch has taken over the responsibility for the ‘TT-Guss’ project and will be supported by our team members Julien Lecompagnon and Sruthi Krishna K P. Philipp has gathered a lot of experience in the RnD of laser-based active thermography over the last 6 years at BAM8.3 - Thermographic Methods and his expertise is therefore invaluable for successful continuation of the project! What is the TT-Guss project about❓ 🔬 TT-Guss focuses on the development of a laser thermography-based method for the non-destructive testing of cast products. This approach aims to detect near-surface and surface imperfections in rough-surfaced castings and offers analternative to magnetic particle and penetration testing. This is particularly relevant for small and medium-sized enterprises (SMEs) in the foundry industry that require reliable, fast, and cost-effective quality control methods before further machining takes place. The project aims to make laser thermography a practical and efficient method, particularly for complex geometries, with a focus on:  - High sensitivity to near-surface defects  - Minimizing surface influence on test results  - Automated and high-speed testing capabilities for integration into the production line  🔎 We are looking forward to the endeavor over the next 1.5 years to bring the potential of laser thermography to quality control in the foundry industry! If you have any questions, feedback, or are interested in collaboration, please do not hesitate to reach out!   #LaserThermography #NonDestructiveTesting #NDT #Casting #QualityControl #BAM #MaterialTesting #Innovation #Research #FoundryIndustry #TTGuss 

“Those images with the infrared camera are remarkable. They are really really good. It is shocking to see these images…” – says Allen Hall in one of the latest Weather Guard Lightning Tech Podcasts. The infrared images that are available online and free of charge in the KI-VISIR data set were discussed in the interview with our colleague Michael Stamm and with Rene Harendt from Romotioncam. The data set is part of the BAM8.3 - Thermographic Methods recent work that provides opportunity to use thermographic data for the inspection of wind turbine rotor blades. An important discussion point was the technical feasibility for the industry and the scientific questions that we are working on at Bundesanstalt für Materialforschung und -prüfung to explore the viability of passive thermography ready for the wind turbine blades inspection market.

Do you want to push the boundaries of technology and use ultrasound to look (or “hear”) inside a component? Department 8.4 at BAM researches acoustic and electromagnetic methods for non-destructive material testing. Ultrasonic testing without direct contact with the test object is a particularly exciting challenge. If you would like to advance our research work with your knowledge of measurement technology or acoustics, then you have come to the right place! To characterize our newly developed phased array probe, you will measure the sound field using state-of-the-art methods such as optical microphones in the frequency range up to 1 MHz. You will then test this (and other) transducers on real components made of carbon-fiber-reinforced plastics to ensure component reliability. We also offer the opportunity to write a thesis on this topic. It is recommended that you complete an internship (ideally a compulsory internship) to familiarize yourself with the subject before starting your thesis.
