  • Determination of Residual Stresses in Plate Material by Layer Removal with Machine-integrated Measurement 
    Dreier, Steven; Denkena, Berend (Amsterdam : Elsevier B.V., 2014)
    Structural aircraft components are usually manufactured from rolled plate material. Despite a stress relief treatment residual stress remains in the plates. This can result in distortions of the workpiece after the final ...
  • Effect of sandblasting on the surface roughness and residual stress of 3Y-TZP (zirconia) 
    Finger, Christin; Stiesch, Meike; Eisenburger, Michael; Breidenstein, Bernd; Busemann, Sarah; Greuling, Andreas ([Cham] : Springer International Publishing, 2020)
    A defined surface roughness is important for the adhesive bonding of veneering ceramic to zirconia frameworks. Thus, we investigated the effects that sandblasting has upon the surface roughness and residual stress of ...
  • Elementary studies on the inducement and relaxation of residual stress 
    Denkena, Berend; Köhler, Jens; Breidenstein, Bernd; Mörke, Tobias (Amsterdam : Elsevier BV, 2011)
    In order to qualify residual stress relaxation as an indicator of mechanical overloading of machined parts, an individually designed residual stress profile has to be allocated. Even though numerous investigations have ...
  • Estimation of load history by residual stress relaxation 
    Breidenstein, Bernd; Denkena, Berend; Mörke, Tobias; Hockauf, R. (Amsterdam : Elsevier, 2015)
    Focusing on the impact of machining on structural integrity and fatigue life of components the surface and subsurface properties are of major importance. It is well known that machining induced residual stresses have a ...
  • Increased performance in high speed turning of Inconel 718 by laser structuring of PcBN tools 
    Denkena, Berend; Grove, Thilo; Krödel, Alexander; Ellersiek, Lars (Amsterdam : Elsevier B.V., 2018)
    In order to improve the cutting performance of PcBN tools, the cutting edge is prepared e.g. by grinding or brushing. Since PcBN is the second hardest material besides diamond, mechanical preparation of PcBN tools is ...
  • The influence of deep rolling on the surface integrity of AISI 1060 high carbon steel 
    Abrão, A.M.; Denkena, Berend; Köhler, Jens; Breidenstein, Bernd; Mörke, Tobias (Amsterdam : Elsevier, 2014)
    The aim of this work is to study the influence of selected deep rolling parameters (rolling pressure and number of passes) on the surface integrity of fully annealed AISI 1060 high carbon steel. In addition to the mechanical ...
  • Investigations on Residual Stresses within Hot-Bulk-Formed Components Using Process Simulation and the Contour Method 
    Behrens, Bernd-Arno; Gibmeier, Jens; Brunotte, Kai; Wester, Hendrik; Simon, Nicola; Kock, Christoph (Basel : MDPI, 2021)
    Residual stresses resulting from hot-forming processes represent an important aspect of a component’s performance and service life. Considering the whole process chain of hot forming, the integrated heat treatment provided ...
  • Investigations on tailored forming of aisi 52100 as rolling bearing raceway 
    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)
