  text: '<jats:p>Abstract. 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>'
