  text: "The recent trend towards extensive electric mobility leads to a variety of
    new challenges for the engineering of future vehicle concepts. One particular
    challenge is the additional weight added to the vehicle by the battery, which
    stands in direct contrast to the existing customer expectation of a high driving
    range. The reduction of the total vehicle weight is driven by the extensive use
    of ultra-high-strength steels in thin sheet thicknesses in car body construction.
    Resistance spot welding is the dominant joining process in steel-intensive lightweight
    construction due to its high degree of automation, process reliability and the
    associated economic efficiency.\r\nIn order to comply limitations of the space
    in the vehicle body and to ensure the most efficient use of materials in lightweight
    construction, joints are used that connect several sheets with a single spot weld.
    This leads to new challenges for the prediction of the load-bearing capacity and
    failure behaviour under crash loading.  \r\nThis paper presents a systematic characterisation
    of 3 sheet steel joints in order to find formulary, empirical relationships between
    the load-bearing capacity of the joint and the affecting parameters.\r\nNumerical
    simulations are carried out in order to clarify the causes of occurring phenomena
    in experiments. For this purpose, influencing variables such as joint strength,
    joint arrangement, sheet thickness, sheet strength, load type and load case on
    the load bearing capacity and failure behaviour are identified.\r\nFurthermore,
    the extent to which the behaviour of 2-sheet joints can be transferred to 3-sheet
    joints is investigated. A formulary correlation enables a quick and inexpensive
    estimates of the load-bearing capacity of 3-sheet metal connections. These models
    can be used for a computer-efficient simulation of components with three layered
    spot welded joints."
