Strength and fatigue properties of stainless steel clinched joints
(English)Manuscript (preprint) (Other academic)
Tensile strength and fatigue life of clinched overlap joints in austenitic stainless steels have been investigated. Tensile tests show that round clinches have higher strength than rectangular and that rectangular clinches have different strength depending on the loading angle. Tensile tests on rectangular clinches in different sheet thicknesses and different steels showed that clinches made in thicker sheets had higher strength and that the strength differed only slightly between clinches in the three different tested steels. Staircase fatigue testing was performed to find the fatigue limit for 2 million cycles. Round clinches were found to have more than twice the fatigue limit compared to rectangular ones. In fatigue the material seemed to be more important, the most stable grade exhibits the highest fatigue life and the least stable the lowest.
