    Denkena, Berend; Dittrich, Marc-André; Uhlich, Florian (Amsterdam : Elsevier B.V., 2016)
    New integrated sensors and connected machine tools generate a tremendous amount of in-depth process data. The continuous transformation of the obtained data into deployable machining knowledge allows for faster ramp-ups, ...
  • Entwicklung eines Modells zur Vorhersage stationärer Transitionsmechanismen in Niederdruckturbinen unter dem Einsatz von skalenauflösenden Simulationen 
    Müller-Schindewolffs, Christoph (Hannover : Institut für Turbomaschinen und Fluid-Dynamik, 2022)
    Steady RANS simulations form the backbone of the aerodynamic turbomachinery design tool chain. They combine a fast response with the ability to describe three-dimensional geometries. However, they are based on approximations ...
  • Evaluation and modeling of the fatigue damage behavior of polymer composites at reversed cyclic loading 
    Koch, Igor; Just, Gordon; Brod, Martin; Chen, Jiuheng; Doblies, Audrius; Dean, Aamir; Gude, Maik; Rolfes, Raimund; Hopmann, Christian; Fiedler, Bodo (Basel : MDPI AG, 2019)
    Understanding the composite damage formation process and its impact on mechanical properties is a key step towards further improvement of material and higher use. For its accelerated application, furthermore, practice-related ...
  • Modeling the wetting behavior of grinding wheels 
    Wichmann, Marcel; Eden, Michael; Zvegincev, Dennis; Wiesener, Frederik; Bergmann, Benjamin; Schmidt, Alfred (London : Springer, 2023)
    Helical flute grinding is an important process step in the manufacturing of cylindrical cemented carbide tools where the use of cooling lubricants is a defining factor determining process performance. Finding optimal ...
  • Multi-scale positioning control model of a novel fluid dynamic drive by coupling process and adapted CFD models 
    Möhring, H.-C.; Kayapinar, H.; Denkena, Berend (Amsterdam : Elsevier BV, 2012)
    In this paper multi-scale modeling of a novel fluid dynamic planar positioning system is described and compared with a simplified plant model. The multi-scale model is realized by coupling a mechatronic simulation model ...
  • Multi-temporal time-dependent terrain visualization through localized spatial correspondence parameterization 
    Dalyot, Sagi; Doytsher, Y. (Basel : MDPI AG, 2013)
    Visualizing quantitative time-dependent changes in the topography requires relying on a series of discrete given multi-temporal topographic datasets that were acquired on a given time-line. The reality of physical phenomenon ...
  • Multiple scale modeling of Al2O3 thin film growth in an ion beam sputtering process 
    Turowski, Marcus; Jupé, Marco; Melzig, Thomas; Pflug, Andreas; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    A multiple scale model approach is presented in order to investigate Al2O3 thin film growth in the framework of an existing Ion Beam Sputtering (IBS) coating process. Therefore, several simulation techniques are combined ...
  • Optimization of novel phase separating IBS process 
    Jupé, Marco; Willemsen, Thomas; Malobabic, Sina; Schuba, Kornelia; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    During the last years, optical low loss components gained more and more industrial interest and led to novel approaches for the production in optical coating technology. The application of filtered deposition technologies ...
  • Opto-Thermal simulation model for optimizing laser-excited remote phosphor systems 
    Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, Wash. : SPIE, 2018)
    A new family of lighting products is developed as laser diodes replace LEDs in the remote phosphor configuration. The resulting lighting systems, also known as laser-excited remote phosphor systems, exhibit advanced ...
