  • 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 ...
  • Evaluation of common tests for fracture characterisation of advanced high-strength sheet steels with the help of the FEA 
    Peshekhodov, Ilya; Dykiert, M.; Vucetic, Milan; Behrens, Bernd-Arno (Bristol : Institute of Physics Publishing, 2016)
    The paper presents results of evaluation of common tests for fracture characterization of advanced high-strength sheet steels with the help of the FEA. The tests include three in-plane shear tests, two uniaxial tension ...
  • How to fragment peralkaline rhyolites: Observations on pumice using combined multi-scale 2D and 3D imaging 
    Hughes, Ery C.; Neave, David A.; Dobson, Katherine J.; Withers, Philip J.; Edmonds, Marie (Amsterdam : Elsevier B.V., 2017)
    Peralkaline rhyolites are volatile-rich magmas that typically erupt in continental rift settings. The high alkali and halogen content of these magmas results in viscosities two to three orders of magnitude lower than in ...
  • Influence of process parameters on the hot stamping of carbon-martensitic chromium steel sheets 
    Behrens, Bernd-Arno; Hübner, S.; Sunderkötter, C.; Gebel, L.; Gnaß, S.; Berndt, G.; Trimborn, C.; Pfeffer, C. (Bristol : Institute of Physics Publishing, 2018)
    Hot-stamped components are an important part in steel-intensive automobile lightweight design in which the use of the heat-treatable steel 22MnB5 has been established. However, the field of application is limited by the ...
  • A novel multiparametric imaging approach to acute myocarditis using T2-mapping and CMR feature tracking 
    Baeßler, Bettina; Treutlein, Melanie; Schaarschmidt, Frank; Stehning, Christian; Schnackenburg, Bernhard; Michels, Guido; Maintz, David; Bunck, Alexander C. (London : BioMed Central Ltd., 2017)
    Background: The aim of this study was to evaluate the diagnostic potential of a novel cardiovascular magnetic resonance (CMR) based multiparametric imaging approach in suspected myocarditis and to compare it to traditional ...
  • A study on electrofuels in aviation 
    Goldmann, Andreas; Sauter, Waldemar; Oettinger, Marcel; Kluge, Tim; Schröder, Uwe; Seume, Jörg R.; Friedrichs, Jens; Dinkelacker, Friedrich (Basel : MDPI AG, 2018)
    With the growth of aviation traffic and the demand for emission reduction, alternative fuels like the so-called electrofuels could comprise a sustainable solution. Electrofuels are understood as those that use renewable ...
  • Testing of Formed Gear Wheels at Quasi-Static and Elevated Strain Rates 
    Clausmeyer, Till; Gutknecht, Florian; Gerstein, Gregory; Nürnberger, Florian (Amsterdam [u.a.] : Elsevier, 2020)
    Geared components can be manufactured from sheet metals by sheet-bulk metal forming. One relevant load case in service are overload events, which might induce elevated strain rates. To determine the characteristic hardening ...
