  text: "<jats:title>Abstract</jats:title>\r\n          <jats:p>The effects of corrosion
    on clinched joints are not completely understood yet. Recent research indicates
    that galvanic corrosion can actually enhance the fatigue life of clinched joints.
    It is then of significant interest to investigate the effects of another corrosion
    phenomenon, pitting corrosion, on the fatigue behavior of clinched joints. Pitting
    corrosion occurs in passive metals and can lead to stress concentrations. In the
    present study, the effects of pitting corrosion are investigated by using Lemaitre’s
    two-scale fatigue model with a 2D geometry of clinched joints. A slip condition
    is applied as a boundary condition to simplify the clinched joint model and reduce
    the computational cost of solving the contact mechanics problem. Additionally,
    a method to determine the damage strength and the damage exponent used in the
    two-scale damage model is introduced. Numerical simulations reveal that pitting
    corrosion reduces the fatigue life of clinched joints, particularly when it occurs
    on the internal surface in the neck area.</jats:p>"

  text: Galvanic corrosion is a destructive process between dissimilar metals. The
    present paper presents a constructed numerical test case to simulate galvanic
    corrosion of two dissimilar metals. This test case is used to study the accuracy
    of different implementations to track the dissolving anode boundary. One technique
    is to numerically simulate a mesh displacement based on the prescribed displacement
    at the anode boundary. The second method is to adjust only the boundary elements.
    Re-meshing after a certain number of time steps is applied to both implementations.
    They produce similar results for an electrical and electrochemical field problem.
    This work shows that mesh smoothing does not result in higher accuracy when modeling
    a moving anode front. Adjusting only the boundary elements is sufficient when
    frequent re-meshing is used.
