    A sharp-interface model employing the extended finite element method is presented. It is designed to capture the prominent γ-γ′ phase transformation in nickel-based superalloys. The novel combination of crystal plasticity ...
  • Long, Yangyang; Arndt, Matthias; Dencker, Folke; Wurz, Marc; Twiefel, Jens; Wallaschek, Jörg (Rio de Janeiro : Elsevier, 2022)
    Due to the complex mechanisms, the ultrasonic (US) wire bonding process is usually optimized in the way of varying the processing parameters including normal force, US power, and processing time. In this study, a new way ...
  • Ley, Peer-Phillip; Wolf, Alexander; Lachmayer, Roland; Knöchelmann, Marvin (Basel : MDPI, 2022)
    The integration of optical technologies into once purely mechatronic systems enables innovative functions, but simultaneously increases the complexity of previous mechatronic system development. Therefore, a process has ...
  • El Maanaoui, Hamid (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Elastomers are able to deform elastically under tensile and compressive loads up to large deformations. For this reason they are often used for industrial purposes (tire production, rubber bands, sealing rings, etc.). The ...
  • Zhuang, Xioaying; Zheng, Fei; Zheng, Hong; Jiao, Yu-Yong; Rabczuk, Timon; Wriggers, Peter (New York, NY [u.a.] : Wiley, 2021)
    Irregular polygon shapes (eg, with small edges or small angles) are usually encountered in the contact simulation of discrete block systems. Treatment of irregular polygons in contact detection process has critical effects ...
  • Eggers, Torben; Kim, Hye Rim; Bittner, Simon; Friedrichs, Jens; Seume, Joerg R. (Basel : MDPI, 2020)
    In modern aircraft engines, the low-pressure compressor (LPC) is subjected to a flow characterized by strong wakes and secondary flows from the upstream fan. This concerns ultra-high bypass ratio (UHBR) turbofan engines, ...
  • Denkena, B.; Breidenstein, B.; Krödel, A.; Prasanthan, V. (Berlin : Springer, 2020)
    The requirements for massive high-performance components are constantly increasing. In addition to the reduction of component weight, requirements such as smaller design, more functionality and longer lifetime are increasing. ...
  • Behrens, Bernd-Arno; Duran, Deniz; Matthias, Tim; Ross, Ingo (Berlin : Springer, 2020)
    Lightweight multi-material components are of great importance for the transport industry. Not only the component’s weight can be decreased, but also its local properties can be adapted to different loading profiles. Tailored ...
  • Szyniszewski, Stefan; Vogel, Rene; Bittner, Florian; Jakubczyk, Ewa; Anderson, Miranda.; Pelacci, Manuel; Chinedu, Ajoku; Endres, Hans-Josef; Hipke, Thomas (London : Nature Publishing Group, 2020)

  • Schüller, Philipp Marius (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)
    Im Rahmen dieser Arbeit wird der axiale, dynamische Dicht-kontakt von Rechteckdichtringen (REDR) in Drehdurchführungen von Kfz-Getrieben untersucht. Im Fokus steht der Einfluss struktu-rierter Dichtkontaktflächen auf Reibung ...
  • Denkena, Berend; Abele, Eberhard; Brecher, Christian; Dittrich, Marc-André; Kara, Sami; Mori, Masahiko (Oxford : Elsevier, 2020)
    The growing global energy demand from industry results in significant ecological and economical costs. Aiming to decrease the impact of machining operations, an increasing number of research activities and publications ...
  • Thürer, Susanne Elisabeth; Peddinghaus, Julius; Heimes, Norman; Bayram, Ferdi Caner; Bal, Burak; Uhe, Johanna; Behrens, Bernd-Arno; Maier, Hans Jürgen; Klose, Christian (Basel : MDPI AG, 2020)
    A novel co-extrusion process for the production of coaxially reinforced hollow profiles has been developed. Using this process, hybrid hollow profiles made of the aluminum alloy EN AW-6082 and the case-hardening steel ...
  • Töller, Felix; Löhnert, Stefan; Wriggers, Peter (Basel : MDPI AG, 2020)
    Forming of hybrid bulk metal components might include severe membrane mode deformation of the joining zone. This effect is not reflected by common Traction Separation Laws used within Cohesive Zone Elements that are usually ...
  • Behrens, Bernd-Arno; Hübner, Sven; Rosenbusch, Daniel.; Müller, Philipp (Basel : MDPI AG, 2020)
    Within the scope of the transregional collaborative research centre TCRC73, the effects of an oscillation superimposed forming process for the production of a demonstrator component are investigated. Previous studies in ...
  • Grajczak, Jan; Nowroth, Christian; Nothdurft, Sarah; Hermsdorf, Jörg; Twiefel, Jens; Wallaschek, Jörg; Kaierle, Stefan (Basel : MDPI AG, 2020)
    Welding by laser beam is a method for creating deep and narrow welds with low influence on the surrounding material. Nevertheless, the microstructure and mechanical properties change, and highly alloyed materials are prone ...
  • Coors, Timm; Mildebrath, Maximilian; Büdenbender, Christoph; Saure, Felix; Faqiri, Mohamad Yusuf; Kahra, Christoph; Prasanthan, Vannila; Chugreeva, Anna; Matthias, Tim; Budde, Laura; Pape, Florian; Nürnberger, Florian; Hassel, Thomas; Hermsdorf, Jörg; Overmeyer, Ludger; Breidenstein, Berd; Denkena, Berend; Behrens, Bernd-Arno; Maier, Hans Jürgen; Poll, Gerhard (Basel : MDPI AG, 2020)
