  • Damage detection for wind turbine rotor blades using airborne sound 
    Krause, Thomas; Ostermann, Jörn (Hoboken, NJ : Wiley, 2020)
    When operating a wind turbine, damage of rotor blades is a serious problem. Undetected damages are likely to increase overtime, and therefore, the safety risks and economical burdens also increase. A monitoring system, ...
  • Energetic damage analysis regarding the fatigue of concrete 
    Bode, Matthias; Marx, Steffen (Malden, Mass. : Wiley, 2020)
    Due to the visco-elasto-plastic material behavior, the added energy to concrete specimens during fatigue tests is transformed into another form of energy. Besides the description of the energetic material behavior of ...
  • Experimental investigations on the fatigue resistance of automatically welded tubular X-joints for jacket support structures 
    Schürmann, K.; Schaumann, P.; Pittner, A.; Rethmeier, M. (Bristol : IOP Publ., 2020)
    The development within the offshore wind sector towards more powerful turbines combined with increasing water depth for new wind parks is challenging both the designer as well as the manufacturer of bottom fixed support ...
  • Fatigue behaviour of grouted connections at different ambient conditions and loading scenarios 
    Schaumann, Peter; Raba, Alexander; Bechtel, Anne (London : Elsevier Ltd., 2017)
    Grouted connections are frequently used as structural detail of offshore wind turbines and platforms for the load transferring connection between piles and support structure. At latticed substructures this connection is ...
  • Mechanical Integrity of Steel Discs with Corrosion Pits 
    Urbano, Jose; Golowin, Andrej; Löhnert, Stefan; Bestle, Dieter (Les Ulis : EDP Sciences, 2018)
    Currently, prediction of crack initiation by corrosion pits is only possible by assuming regular geometrical shapes, such as semi-spheres or semi-ellipsoids. Moreover, typical fatigue life diagrams associate the crack ...
  • Microstructural evolution and functional fatigue of a Ti–25Ta high-temperature shape memory alloy 
    Maier, Hans Jürgen; Karsten, Elvira; Paulsen, Alexander; Langenkämper, Dennis; Decker, Peer; Frenzel, Jan; Somsen, Christoph; Ludwig, Alfred; Eggeler, Gunther; Niendorf, Thomas (Cambridge : Cambridge University Press, 2017)
    Titanium–tantalum based alloys can demonstrate a martensitic transformation well above 100 °C, which makes them attractive for shape memory applications at elevated temperatures. In addition, they provide for good workability ...
  • Structural Change Identification at a Wind Turbine Blade using Model Updating 
    Schröder, Karsten; Grove, Saskia; Tsiapoki, Stavroula; Gebhardt, Cristian G.; Rolfes, Raimund (Bristol : IOP Publ., 2018)
    In this paper, a damage and ice accretion localization method based on finite element model updating is tested using the example of a wind turbine blade. Both eigenfrequencies in combination with mode shapes and a new ...
