  text: "Joining technology is regarded as a key technology for reducing energy consumption
    and CO2 imitation as well as the use of innovative materials and development of
    new, resource-saving products. Punch riveting is a widely used and established
    joining process in many sectors. The white and brown goods, electrical engineering,
    construction and, in particular, the automotive industry are some of the sectors
    mentioned here.\r\n\r\nSince the design and assessment of punch rivet components
    with regard to structural durability can only be carried out experimentally using
    prototypes due to a lack of experience and calculation concepts, the improvement
    of this uneconomical and time-consuming procedure is the goal of this contribution.\r\n\r\nTherefore,
    a numerical simulation and design method for cyclically loads punched riveted
    joints shall be introduced. This concept shall be based on the notch strain concept.\r\n\r\nThe
    following steps are necessary to achieve the goal shown above:\r\n\r\n    Tensile
    tests on all materials involved in the joint for determination of tensile strength
    and quasi-static stress-strain curves\r\n    Estimation of the cyclic material
    properties from the tensile strength in order to obtain the strain-life curve
    and the cyclic stress-strain curve\r\n    Estimation of mean stress sensitivity
    from the tensile strength to conduct an amplitude transformation for variable
    amplitude loadings.\r\n    Execution of a 2D forming simulation of the joining
    process to determine the geometry and the stresses and degrees of deformation
    present in the connection\r\n    Transferring the results of the forming simulation
    into a static-mechanical load simulation for determining the relation between
    the external load and the elastic-plastic strain at the critical point\r\n    Estimation
    of the service life by means of the damage parameter Wöhler curves calculated
    from the strain-life curve\r\n\r\nIn order to verify the simulation and calculation
    method, service life investigations have been carried out on punched riveted components
    under constant and variable amplitude load.\r\n\r\nThe test results, as well as
    the workflow through the fatigue assessment and its accuracy in estimation the
    fatigue life will be shown in this contribution."
