8-MW wind turbine tower computational shell buckling benchmark. Part 1: An international ‘round-robin’ exercise

Sadowski, Adam J.; Seidel, Marc; Al-Lawati, Hussain; Azizi, Esmaeil; Balscheit, Hagen; Böhm, Manuela; Chen, Lei; van Dijk, Ingmar; Doerich-Stavridis, Cornelia; Fajuyitan, Oluwole Kunle; Filippidis, Achilleas; Fischer, Astrid Winther; Fischer, Claas; Gerasimidis, Simos; Karampour, Hassan; Kathirkamanathan, Lijithan; Marten, Frithjof; Mihara, Yasuko; Mishra, Shashank; Sakharov, Volodymyr; Shahini, Amela; Subramanian, Saravanan; Topkaya, Cem; Wagner, Heinz Norbert Ronald; Wang, Jianze; Wang, Jie; Yadav, Kshitij Kumar; Yun, Xiang; Zhang, Pan (Oxford [u.a.] : Elsevier Science, 2023)

An assessment of the elastic-plastic buckling limit state for multi-strake wind turbine support towers poses a particular challenge for the modern finite element analyst, who must competently navigate numerous modelling ...
The analytical beam element model: novel approach for fast calculation of vibrations in electric machines

Gerlach, Martin Enno; de Barros, Allan; Huang, Xudong; Langfermann, Markus; Ponick, Bernd; Ebrahimi, Amir (Wien [u.a.] : Springer, 2023)

The vibration and acoustic behavior of electric machines is an important aspect of the design process. A crucial part of the modeling is the correct prediction of the stator’s vibration behavior, characterized by the ...
A comprehensive ﬁnite element framework for the progressive damage analysis of ﬁber metal laminate bolted joints under static and cyclic loading: theory and experimental validation

Gerendt, Christian (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)

To improve the robustness of ﬁber-reinforced plastics (FRP) in bolted joints, local metal-hybridization of the FRP laminate can be performed to obtain an FRP-based ﬁber metal laminate (FML) of increased bearing strength. ...
Computationally Efficient Buckling Analysis of Damaged Composite Sandwich Panels in Wind Turbine Blades

Prigge, Felix; Rosemeier, Malo; Balzani, Claudio (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021-05-28)

Major parts of a wind turbine rotor blade are designed as sandwich panels, which consist of thin face sheets and a thick sandwich core. The face sheets are normally made of glass fiber reinforced polymer (FRP) laminates ...
Convergence behavior of 3D finite elements for Neo-Hookean material

Stein, Erwin; Sagar, Gautam (Bingley : Emerald Group Publishing Ltd., 2008)

Purpose: The purpose of this paper is to examine quadratic convergence of finite element analysis for hyperelastic material at finite strains via Abaqus-UMAT as well as classification of the rates of convergence for iterative ...
Effects of fibre misalignment on the stability of double-curved composites

Stüven, Jan-Lukas; Heimbs, Sebastian; Schmidt, Carsten (Amsterdam [u.a.] : Elsevier, 2023)

In the context of developing a novel technology for the automated production of continuously draped preforms, the effects of fibre misalignment on the stability of double-curved, unidirectional plies are investigated. The ...
Finite element analysis based on a parametric model by approximating point clouds

Xu, Wei; Neumann, Ingo (Basel : MDPI AG, 2020)

Simplified models are widely applied in finite element computations regarding mechanical and structural problems. However, the simplified model sometimes causes many deviations in the finite element analysis (FEA) of ...
Finite element formulations for large strain anisotropic material with inextensible fibers

Wriggers, Peter; Schröder, J.; Auricchio, F. (Heidelberg : Springer Verlag, 2016)

Anisotropic material with inextensible fibers introduce constraints in the mathematical formulations. This is always the case when fibers with high stiffness in a certain direction are present and a relatively weak matrix ...
Impact of intraprosthetic drilling on the strength of the femoral stem in periprosthetic fractures: A finite element investigation

Brand, Stephan; Bauer, Michael; Petri, Maximilian; Schrader, Julian; Maier, Hans Jürgen; Krettek, Christian; Hassel, Thomas (London : SAGE Publications Ltd., 2016)

Treatment of periprosthetic femur fractures after total hip arthroplasty remains a major challenge in orthopedic surgery. Recently, a novel surgical technique using intraprosthetic screw fixation has been suggested. The ...
Intelligent calibration of static FEA computations based on terrestrial laser scanning reference

Xu, Wu; Bao, Xiangyu; Chen, Genglin; Neumann, Ingo (Basel : MDPI AG, 2020)

The demand for efficient and accurate finite element analysis (FEA) is becoming more prevalent with the increase in advanced calibration technologies and sensor-based monitoring methods. The current research explores a ...
Numerical computation of magnetic fields applied to magnetic force microscopy

Preisner, Thomas; Greiff, Michael; Bala, Uzzal Binit; Mathis, Wolfgang (Bingley : Emerald Group Publishing Ltd., 2009)

Purpose - The purpose of this paper is to introduce a method which allows the calculation of the interactions of tip and sample of a magnetic force microscope as a first step to increase the accuracy of this technique. ...
Numerical investigations of stress shielding in total hip prostheses

Behrens, Bernd-Arno; Wirth, C.J.; Windhagen, H.; Nolte, I.; Meyer-Lindenberg, Andrea; Bouguecha, Anas (London : SAGE Publications Ltd., 2008)

Aseptic loosening of the prosthesis is still a problem in artificial joint implants. The loosening can be caused by, among other factors, resorption of the bone surrounding the prosthesis owing to stress shielding. In order ...
Numerical modelling of electrostatic force microscopes considering charge and dielectric constant

Bala, Uzzal Binit; Greiff, Michael; Preisner, Thomas; Mathis, Wolfgang (Bingley : Emerald Group Publishing Ltd., 2009)

Purpose - The purpose of this paper is to present a hybrid numerical simulation approach for the calculation of potential and electric field distribution considering charge and dielectric constant. Design/methodology/ ...
