  • Goldmann, Andreas; Sauter, Waldemar; Oettinger, Marcel; Kluge, Tim; Schröder, Uwe; Seume, Jörg R.; Friedrichs, Jens; Dinkelacker, Friedrich (Basel : MDPI AG, 2018)
    With the growth of aviation traffic and the demand for emission reduction, alternative fuels like the so-called electrofuels could comprise a sustainable solution. Electrofuels are understood as those that use renewable ...
  • Aboulfotoh, Noha; Twiefel, Jens (Basel : MDPI, 2018)
    This study presents theoretical investigations on the effectiveness criteria for piezoelectric energy harvesters (PEHs) under volume constraints. Firstly, the importance of the volume consideration is investigated. The ...
  • Ahrens, M.; Fischer, R.; Dagen, M.; Denkena, Berend; Ortmaier, Tobias (Amsterdam : Elsevier, 2013)
    Using conventional grinding wheels, wheel-sided chatter vibration is one of the limiting factors in terms of productivity and surface finish. Initial vibration related to the dynamic behavior of the machine tool copy on ...
  • Marhenke, Torben; Sanabria, Sergio J.; Chintada, Bhaskara Rao; Furrer, Roman; Neuenschwander, Jürg; Goksel, Orcun (Basel : MDPI AG, 2019)
    Medical ultrasonic arrays are typically characterized in controlled water baths using measurements by a hydrophone, which can be translated with a positioning stage. Characterization of 3D acoustic fields conventionally ...
  • Denkena, Berend; Gümmer, Olaf (Amsterdam : Elsevier, 2013)
    Within the Collaborative Research Centre 489 at the Leibniz Universitaet Hannover a new and innovative process chain for the manufacture of crankshafts is being investigated. By burr-free and near-net-shaped precision ...
  • Nyhuis, Peter; Vogel, Markus (Bingley : Emerald Group Publishing Ltd., 2006)
    Purpose - To provide a model for precise logistic controlling of one-piece flow processes and for the description of the interactions between logistic performance measures. The developed method can help manufacturing ...
  • Denkena, Berend; Flöter, F. (Amsterdam : Elsevier BV, 2012)
    In the re-contouring process of aircraft engine components, the unknown geometry and inhomogeneous material properties of the workpiece are major challenges. For this reason a new repair process chain is supposed which ...
  • Zhou, Shuwei; Zhuang, Xiaoying (Amsterdam : Elsevier, 2018)
    In this study, we present an adaptive phase field method (APFM) for modeling quasi-static crack propagation in rocks. Crack initiation due to positive strains is considered, and a numerical simulation is implemented using ...
  • Leuteritz, Georg; Lachmayer, Roland (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    Individually shaped light distributions become more and more important in lighting technologies and thus the importance of additively manufactured reflectors increases significantly. The vast field of applications ranges ...
  • Alfred, Irene; Nicolaus, Martin; Hermsdorf, Jörg; Kaierle, Stefan; Möhwald, Kai; Maier, Hans Jürgen; Wesling, Volker (Amsterdam : Elsevier B.V., 2018)
    Components in aircraft engines and gas turbines are exposed to extreme conditions in order to increase performance and efficiency of the overall engine, hence there is an increasing need for cost-effective and time-efficient ...
  • Behrens, Bernd-Arno; Bouguecha, Anas; Vucetic, Milan; Chugreev, Alexander (Les Ulis : E D P Sciences, 2016)
    In the recent decades the finite element method has become an essential tool for the cost-efficient virtual process design in the metal forming sector in order to counter the constantly increasing quality standards, ...
  • Gryshkov, O.; Müller, M.; Leal-Marin, S.; Mutsenko, V.; Suresh, S.; Kapralova, V.M.; Glasmacher, B. (Bristol : Institute of Physics Publishing, 2019)
    Tissue engineering and cell-based therapy approaches require artificial scaffolds as extracellular matrix (ECM) and three-dimensional (3D) environment for clinically relevant cells to attach, be metabolically active and ...
  • Budziak, Kinga (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2015)
    This project evaluates the sutability and practicality of the program Athena Vortex Lattice (AVL) by Mark Drela. A short user guide was written to make it easier (especially for stu-dents) to get started with the program ...
  • Wolff, T.; Ernst, Benedikt; Seume, Jörg R. (Bristol : IOP Publishing Ltd., 2014)
    The length of wind turbine rotor blades has been increased during the last decades. Higher stresses arise especially at the blade root because of the longer lever arm. One way to reduce unsteady blade-root stresses caused ...
  • Frädrich, Thomas; Pachow-Frauenhofer, Julia; Fiege, Torsten; Nyhuis, Peter (Bingley : Emerald Group Publishing Ltd., 2011)
    Purpose - The purpose of this paper is to transfer the idea of changeability to a concrete technical application. Design/methodology/approach - Based on the definition of changeability on a factory level, a transformation ...
  • Schwerdt, Lukas; Hauptmann, Thomas; Kunin, Artsem; Seume, Jörg R.; Wallaschek, Jörg; Wriggers, Peter; Panning-von Scheidt, Lars; Löhnert, Stefan (Amsterdam : Elsevier BV, 2017)
    This paper presents an integrated methodology for the analysis of operationally-used turbine blades, incorporating aerodynamic and multiple structural simulations. In jet engines, blade rubbing and erosion lead to deviations ...
  • Gregorian, Hayk (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2019)
    Purpose - This bachelor thesis compares high-speed rail (HSR) transport with air transport. The investigation considers physical fundamentals, energy consumption, environmental impact, infrastructure and investment, market ...
  • Burzlaff, Marcus (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2017-12-13)
    In order to uncover the best kept secret in today’s commercial aviation, this project deals with the calculation of fuel consumption of aircraft. With only the reference of the aircraft manufacturer’s information, given ...
  • Knöchelmann, Marvin; Wolf, Alexander; Kloppenburg, Gerolf; Lachmayer, Roland (Düsseldorf : VDI Verlag GmbH, 2018-06-05)
