Data for "Modelling large deflections through reduced-order multibody structures in the floating frame of reference formulation"

<p dir="ltr">This dataset includes the input and result files of the numerical models used for the paper "Modelling large deflections through reduced-order multibody structures in the floating frame of reference formulation", as well as the scripts used to produce the plots in the paper.</p><p dir="ltr">In this paper, a method for modelling slender structures using the floating frame of reference formulation (FFRF) and reduced-order models generated from 3D solid finite elements (using the Hurty/Craig-Bampton method) is presented. It is based on a multibody approach, such that large deflections can be captured, and interface modes are used to reduce the interface degrees-of-freedom. A general multibody dynamics code - <a href="https://github.com/jgerstmayr/EXUDYN" rel="noreferrer" target="_blank">Exuydn</a> - is used to implement this model.</p><p dir="ltr">The numerical examples include the static analysis of two beam structures (isotropic and composite), for each the following models are compared:</p><ul><li>Exudyn - Reduced-order FFRF model with interface modes</li><li>Exudyn - Reduced-order FFRF model with rigid (RBE2) interfaces</li><li>Exudyn - Reduced-order FFRF model without interface reduction</li><li>Abaqus - Solid C3D20R elements</li><li><a href="https://www.hawc2.dk/" rel="noreferrer" target="_blank">HAWC2</a> - Beam elements-based FFRF model</li></ul><p dir="ltr">More information can be found on the "readme" file.</p><p dir="ltr"><u>List of individual files and licenses:</u></p><ul><li>Folder <b>plots</b>: © Technical University of Denmark 2025 <a href="https://opensource.org/license/mit" rel="noreferrer" target="_blank">MIT</a></li><li>Folder <b>models</b>:</li><li><ul><li>Subfolders <b>funcsExudyn</b> and <b>exudyn</b>: © Technical University of Denmark 2025 <a href="https://opensource.org/license/mit" rel="noreferrer" target="_blank">MIT</a></li><li>Subfolders <b>hawc2</b>, <b>abaqus</b> and <b>exudyn/results</b>: <a href="https://creativecommons.org/licenses/by/4.0/" rel="noreferrer" target="_blank">CCBY-4.0</a></li></ul></li></ul><p><br></p>
