  text: <jats:title>Abstract</jats:title><jats:p>In order to reduce fuel consumption
    and thus pollutant emissions, the automotive industry is increasingly developing
    lightweight construction concepts that are accompanied by an increasing usage
    of aluminum materials. Due to poor weldability of aluminum in combination with
    other materials, mechanical joining methods such as clinching were developed and
    established in series production. In order to predict the relevant characteristics
    of clinched joints and to ensure the reliability of the process, it is simulated
    numerically during product development processes. In this regard, the predictive
    accuracy of the simulated process highly depends on the implemented friction model.
    In particular, the frictional behavior between the sheet metals as well as between
    the sheet metal and clinching tools has a significant impact on the geometrical
    formation of the clinched joint. No testing methods exist that can sufficiently
    investigate the frictional behavior in sheet materials, especially under high
    interface pressures, different relative velocities, and long friction paths, while
    allowing a decoupled consideration of the test parameters. This paper describes
    the development of further testing concepts based on a proven tribo-torsion test
    method for determining friction coefficients between sheet metal materials for
    the simulation of clinching processes. For this purpose, the correlation of interface
    pressure and the relative velocity between aluminum and steel sheet material in
    clinching processes is investigated using numerical simulation. Based on these
    findings, the developed concepts focus on determining friction coefficients at
    interface pressures of the above materials, yield stress, as well as the reproduction
    of the occurring friction conditions between sheet metal materials and tool surfaces
    in clinching processes using tool substitutes. Furthermore, wear investigations
    between sheet metal material and tool surface were carried out in the friction
    tests with subsequent EDX analyses of the frictioned tool surfaces. The developed
    method also allows an optical deformation measurement of the sheet metal material
    specimen by means of digital image correlation (DIC). Based on a methodological
    approach, the test setups and the test systems used are explained, and the functionality
    of the concepts is proven by experimental tests using different sheet metal materials.</jats:p>
