Accurate Finite Element Modeling (FEM) of joints is essential in the design of complex mechanical systems such as automotive body-in-white (BIW) structures, as it plays a critical role in evaluating their performance. Although well-established techniques exist for modeling rotationally symmetric joints, there remains a significant gap in effectively modeling non-rotationally symmetric joints. These joints are particularly relevant in the automotive BIW, where they can better accommodate anisotropic loading conditions. In this study, strategies for modeling non-rotationally symmetric joints were explored using finite element simulations in LS-DYNA. The findings demonstrate that discrete beam elements can capture the anisotropic characteristics of such joints. Two models were tested: a single-beam model for stiffness periodicity every 90°, and a three-beam model for stiffness periodicity every 120°. Force responses, stress distribution, and sheet bending behaviors were analyzed, confirming that discrete beam elements can accurately represent direction-dependent stiffness. These results establish a foundation for developing advanced joint modeling strategies in complex mechanical systems.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.21741/9781644903551-21","year":"2025","title":"Modelling strategies for non-rotationally symmetric joints","author":[{"last_name":"Devulapally","first_name":"Deekshith Reddy","full_name":"Devulapally, Deekshith Reddy","id":"76837"},{"last_name":"Tröster","first_name":"Thomas","full_name":"Tröster, Thomas","id":"553"}],"publication_identifier":{"issn":["2474-395X"]},"publication_status":"published","date_updated":"2026-02-27T10:50:10Z","intvolume":"        52","citation":{"ieee":"D.
