  text: <jats:p>Clinched joints with non-rotationally symmetric geometries exhibit
    orientation-dependent mechanical behavior that is commonly neglected in structural-scale
    simulations. Reuleaux triangle shaped clinched joints, in particular, show pronounced
    in-plane anisotropy depending on their orientation. While such effects have been
    studied at joint and specimen scale, their relevance at the structural level remains
    largely unexplored. In this work, the influence of joint orientation on the bending
    response of a joined structure is investigated using numerical simulations. A
    simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector
    formulation in LS-DYNA is employed, with parameters calibrated from previously
    obtained experimental force displacement data. A hat shaped profile structure
    subjected to three-point bending is analyzed in a parametric study considering
    variations in joint orientation, joint spacing, and profile geometry. The results
    show that joint orientation has little influence during the initial deformation
    phase but becomes increasingly significant at larger displacements, where joint
    behavior governs load transfer. Orientation dependent effects are found to influence
    the global force displacement response and local load redistribution among joints,
    with magnitudes comparable to those induced by changes in joint spacing and structural
    geometry. The findings confirm that joint orientation effects remain relevant
    at the structural level and should be considered in the design of structures assembled
    using non-rotationally symmetric clinched joints.</jats:p>
