Abstract. Corrosion usually has detrimental effects on the longevity of metallic structures. Several corrosion mechanisms exist, which affect the metallic structures differently. Galvanic corrosion is a major corrosion phenomenon that occurs when two dissimilar metals are in contact with each other and with an electrolyte. Due to galvanic corrosion, the less noble metal dissolves which can shorten the service life of the metallic component significantly. However, recent research has shown that corrosion can have a beneficial impact on metal joints. Brief exposure of clinched specimens to a salt spray environment extends the corroded specimen’s fatigue life. The present work introduces a simulation procedure which can numerically predict the effects of corrosion product formation on the fatigue life of clinched joints.
