  text: Non-rotationally symmetrical joints can have different properties that can
    be controlled by the joint orientation. This hypothesis is tested using a Reuleaux
    triangle joint geometry. A tool design is carried out, followed by a numerical
    sensitivity analysis of the tool geometry. Initial tools were manufactured for
    experimental investigations and then adapted based on the findings of the sensitivity
    analysis. The joints are characterized by micrographs, 3D scans, shear tensile
    tests, head tensile tests and three-point bending tests and compared with a round
    geometry. The analysis confirms the hypothesis. Thus, joints with adaptable properties
    can be produced with one tool set.
