  - This study presents a numerical approach using a 3D finite element model to quantify
    the remaining clamp load of a plastic nut joint after a specific time. The viscoelastic
    relaxation of a thermoplastic nut, which is predominantly screwed on a welding
    stud, is described by a material card using Prony Series. Prony Series are derived
    from experimental dynamical mechanical analysis with different moisture and fiber
    contents of the thermoplastic. Since plastic nuts usually do not have preformed
    threads, the increased temperatures and resulting stresses from the thread-forming
    process are considered in the simulation. An FE model is created and verified
    by substrate stress relaxation tests. Experimental clamp load measurements with
    miniature compression load cells verify the clamp load prediction and show a good
    agreement. The developed model is used to analyze the clamp load distribution
    within the threads and reveals an almost even distribution within the threads.@eng
