  text: This paper examines the impact of a rotationally superimposed punch stroke
    on the binding mechanisms of clinched joints of aluminum sheets. As part of the
    development of a method for ensuring the versatility of clinching, an additional
    rotational movement of the punch was introduced as a control variable to influence
    friction in the mechanical joining process. The effect of rotational superimposition
    on the force-displacement curve of the clinching processes was investigated using
    four test variants with different kinematics. The primary objective was to evaluate
    the binding mechanisms that maintain the integrity of the clinched joint. To evaluate
    the force closure of the resulting joint, two testing methods were employed throughout
    the course of the research, non-destructive resistance measurement using four-wire
    sensing method and destructive torsion testing. A crucial factor influencing the
    efficacy of the process is surface cleanliness, as contaminants between joining
    partners can impede the effectiveness of the clinched joint. Therefore, all specimens
    were meticulously cleaned prior to experimentation. This method exhibits promising
    potential in creating clinched joints that align with the demands of flexible
    manufacturing environments.</jats:p>

  text: 'In order to reduce the fuel consumption and consequently the greenhouse emissions,
    the automotive industry is implementing lightweight constructions in the body
    in white production. As a result, the use of aluminum alloys is continuously increasing.
    Due to poor weldability of aluminum in combination with other materials, mechanical
    joining technologies like clinching are increasingly used. In order to predict
    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 affects the geometrical formation of the clinched joint significantly.
    This paper presents a testing method, which enables to determine the frictional
    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 sheets in clinching processes is investigated using numerical
    simulation. Furthermore, the developed testing method focuses on the specimen
    geometry as well as the reproduction of the occurring friction conditions between
    two sheet metal materials in clinching processes. Based on a methodical approach
    the test setup is explained and the functionality of the method is proven by experimental
    tests using sheet metal material EN AW6014. '
