  text: "One of the major topics in the modern automotive industry is reducing emissions
    and increasing the mileage\r\nrange. To tackle this challenge, on the one hand,
    modifying the powertrain system is a possibility, and on the\r\nother hand, lightweight
    design offers various possibilities. Multi-Material Design (MMD) involves designing
    car\r\nbodies that combine different materials that require joining. Given the
    variety of materials, mechanical joining\r\nprocesses are preferred. Especially
    the current development of the Giga/Mega-casting process concerning\r\naluminium
    casting and the subsequent mechanical joining illustrates the challenges of this
    material group. In car\r\nproduction, aluminium castings are mainly made from
    aluminium-silicon (AlSi) alloys. Ultimately, the alloy\r\nsystem's insufficient
    ductility leads to crack initiation during mechanical joining. Cast parts are
    therefore often\r\nused in areas of the car body that are exposed to high-pressure
    loads. For example, self-piercing riveting (SPR) is\r\nused due to its high load-bearing
    capacity. In this study, improved joinability is demonstrated by influencing the\r\nmicrostructure
    through tailored solidification rates and a developed heat-treatment chain strategy
    adapted for\r\nhypoeutectic AlSi systems. Data on microstructure, mechanical,
    and joining properties are used to develop a\r\nsolidification-joining correlation
    for the SPR process across a range of Si contents and solidification rates. The\r\npurpose
    is to develop the ability to produce suitable aluminium castings with sufficient
    joinability, thereby\r\nimproving versatility."

  text: The conduction of structure-borne sound through joints causes energy dissipation.
    The sound reduction index describes this energy loss as a level decrease in the
    particle velocity across series-connected damping elements for which the superposition
    principle applies. This simple model can help to develop a testing method for
    joints based on this characteristic energy loss. In this paper, this model is
    experimentally evaluated for multiple in-series clinched aluminium sheets. Samples
    connected by several clinch points arranged in parallel are investigated experimentally,
    and the results are discussed.
