Tom Lohmüller

Tom pursued his academic journey at the Technical University of Braunschweig, where he earned his master's degree in mechanical engineering and business in 2018. He conducted his bachelor thesis at Volkswagen in Wolfsburg, focusing on fatigue strength within the overall vehicle department of the research and development division. He authored his master's thesis at GOM on the self-calibration of industrial robots using optical measurement technology. Since 2018, Tom has been an integral part of SincoTec. He began as a trainee and quickly advanced to become an assistant to the management board.

Presentation

New challenges and solutions in fatigue strength testing under hydrogen

We will present examples showing the influence of hydrogen on fatigue strength in tension-compression tests, rotating bending tests and tensile strength tests of different materials. Particular attention will be paid to the need to redefine values for fracture mechanics, particularly the challenge of identifying a crack in a pipeline and analyzing in which of the three fracture mechanics areas it is located. However, the determination of these values is very complex due to the different framework conditions such as explosion protection, high pressures (up to 1,000 bar), temperature influences (-60°C-+700°C) and the need to analyze the crack.
