  • Behrens, Bernd-Arno; Nolte, Ingo; Wefstaedt, Patrick; Stukenborg-Colsman, Christina; Bouguecha, Anas (London : Biomed Central Ltd, 2009-04-16)
    Background: There are several numerical investigations on bone remodelling after total hip arthroplasty (THA) on the basis of the finite element analysis (FEA). For such computations certain boundary conditions have to be ...
  • Paggi, Marco; Wriggers, Peter (Cassino : Gruppo Italiano Frattura, 2011)
    In this paper, the phenomenon of intergranular fracture in polycrystalline materials is investigated using a nonlinear fracture mechanics approach. The nonlocal cohesive zone model (CZM) for finite thickness interfaces ...
  • Mähler, Lennart Alexander; Willeke, Tobias; Seume, Joerg R. (Zug : Global Power and Propulsion Society, 2018)
    Riblet structured surfaces can reduce the aerodynamic drag of bodies, which are immersed in fluid flows. A future application of these microscopic grooves with dimensions below 100 μm on axial compressor blades could ...
  • Bouguecha, Anas; Weigel, Nelly; Behrens, Bernd-Arno; Stukenborg-Colsman, Christina; Waizy, Hazibullah (London : Biomed Central Ltd, 2011-07-05)
    Background: The use of artificial endoprostheses has become a routine procedure for knee and hip joints while ankle arthritis has traditionally been treated by means of arthrodesis. Due to its advantages, the implantation ...
  • Petrovic, M.; Riess, W. (London : SAGE Publications Ltd., 1997)
    In this paper, a method for flow calculation in large steam turbines is presented. The method is based on the through-flow theory and the finite element procedure. It includes some extensions and improvements in the form ...
  • Behrens, Bernd-Arno; Bonk, Christian; Peshekhodov, I. (Bristol : Institute of Physics Publishing, 2017)
    The paper presents application of fracture behaviour characterisation results of a dual-phase sheet steel DP600 to an FEA of its deep-drawing for shear fracture prediction. The characterisation results were obtained with ...
  • Raeisian, Leyla; Eggers, Jan Rudolf; Lange, Eckart Matthias; Mattke, Torsten; Bode, Andreas; Kabelac, Stephan (Berlin, Heidelberg : Springer, 2019-04-01)
    Different findings about suitable correlations to describe nanofluid viscosity can be explained based on the research presented in this paper. The effective viscosity of nanofluids is crucial when nanofluids are considered ...
  • Schlobohm, Jochen; Pösch, Andreas; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Examining the geometry of complex industrial free form objects, like a blade integrated disk (blisk) of a jet engine compressor, is currently subject to research. High measurement precision and speed are required and the ...
  • Kornilov, S.; Rempe, N.; Beniyash, Alexander; Murray, Nils (Bristol : Institute of Physics Publishing, 2014)
    The report presents the measurement results of the focused beam brightness in the electron gun with plasma emitter. The beam brightness was approximately 1010 A·m-2·sr-1 under the beam power up to 4 kW and an electron ...
  • Winstroth, J.; Seume, J.R. (Bristol : Institute of Physics Publishing, 2016)
    The manufacture of large wind turbine rotor blades is a difficult task that still involves a certain degree of manual labor. Due to the complexity, airfoil deviations between the design airfoils and the manufactured blade ...
  • Neubauer, Marcus; Han, Xu; Wallaschek, Jörg (London : SAGE Publications Ltd., 2013)
    Synchronized switch damping on inductor offers a high damping performance in a broad frequency range. It consists of an inductor and resistor in a serial configuration, which are connected and disconnected from the ...
  • Wang, Yixiao; Wolfer, Tim; Lange, Alex; Overmeyer, Ludger (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Large scale, planar optronic systems allowing spatially distributed functionalities can be well used in diverse sensor networks, such as for monitoring the environment by measuring various physical quantities in medicine ...
  • Höhl, Martin; Detemple, Daphne; Lyutenski, Stefan; Leuteritz, Georg; Varkentin, Arthur; Schmitt, Heike Andrea; Lenarz, Thomas; Roth, Bernhard; Meinhardt-Wollweber, Merve; Morgner, Uwe (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Optical techniques are effective tools for diagnostic applications in medicine and are particularly attractive for the noninvasive analysis of biological tissues and fluids in vivo. Noninvasive examinations of substances ...
  • Neubauer, Marcus (Warsaw : Polish Academy of Sciences, Institute of Fundamental Technological Research, 2014)
    In vibration control with piezoceramics, a high coupling of the piezoelement with the structure is desired. A high coupling improves the damping performance of passive techniques like shunt damping. The coupling can be ...
  • Gronitzki, M.; Poll, G.W.G. (London : SAGE Publications Ltd., 2007)
    Rectangular seals - a special type of face seals - are currently used in rotating connections of automatic automotive transmissions (double clutch transmissions, continuously variable transmissions, and 6-automated ...
  • Teichel, Sönke (Hannover : Institut für Turbomaschinen und Fluid-Dynamik, 2018)
    To support an active high-lift system for future civil aircraft small, electrically powered compressors are required, which exceed the current state of the art concerning stage loading and compactness. To satisfy the ...
  • Leuteritz, Georg; Lippert, René Bastian; Lachmayer, Roland (Erlangen : Deutsche Gesellschaft für angewandte Optik, 2017-08-04)
    This work examines an approach for the optimization of the optical quality of additively manufactured reflectors. Therefore the parameters of a Selective Laser Melting process, which manipulate surface properties ...
  • Kloppenburg, Gerolf; Roth, Joscha; Wolf, Alexander; Lachmayer, Roland (Düsseldorf : VDI-Verlag, 2016)
    In dieser Arbeit wird ein scannendes Laserprojektionssystem vorgestellt, welches auf drei Laserdioden basiert und der RGB-Projektion in das erweiterte Fahrzeugvorfeld dient. Die projizierten Informationen wie Navigationshinweise ...
  • Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
