Comparison of viscoelasticity models for the prediction of residual stresses in wind turbine rotor blades

Wang, Yixing; Balzani, Claudio (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021-05)

In the composite materials of wind turbine rotor blades, residual stresses develop due to the manufacturing processes [1]. During the curing of the polymeric matrix, chemical shrinkage is present. Moreover, different ...
Identification of material properties for finite element simulation of the deep rolling process applied to welded joints

Heikebrügge, Steffen; Breidenstein, Bernd; Bergmann, Benjamin; Dänekas, Christian; Schaumann, Peter; Schubnell, Jan (Amsterdam [u.a.] : Elsevier, 2022)

During butt welding of structural steels, an inhomogeneous material state across the weld occurs that has a detrimental influence on fatigue strength. In the presented study, the identification of Lemaitre Chaboche ...
Investigations on Additively Manufactured Stainless Bearings

Coors, Timm; Faqiri, Mohamad Yusuf; Saure, Felix; Kahra, Christoph; Buedenbender, Christoph; Peddinghaus, Julius; Prasanthan, Vannila; Pape, Florian; Hassel, Thomas; Herbst, Sebastian; Nuernberger, Florian; Wester, Hendrik; Uhe, Johanna; Breidenstein, Bernd; Denkena, Berend; Behrens, Bernd-Arno; Poll, Gerhard; Maier, Hans Juergen (Basel : MDPI, 2022)

Additive manufacturing with multi-material design offers great possibilities for lightweight and function-integrated components. A process chain was developed in which hybrid steel–steel-components with high fatigue strength ...
A new approach for the prediction of fatigue life in rolling bearings based on damage accumulation theory considering residual stresses

Hwang, Jae-Il; Poll, Gerhard (Lausanne : Frontiers Media SA, 2022)

Today, the service life calculation of rolling bearings is standardized in ISO 281, based on the theory of Lundberg and Palmgren. In the standard calculation method, material properties such as fatigue limit stress were ...
