Abstract The flat-clinching is attracting increasing attentions in the field of lightweight structures because it does not form an exterior protrusion on the bottom sheet like the conventional clinching. In the present research, the flat-clinching process for joining the three-layer sheets is investigated through experimental methods. Sheet specimens were divided into two types based on loading characteristics and employed to produce joint specimens with different sheet configurations. The effects of the sheet configurations on the mechanical characteristics of the clinched joint were analyzed. This study consisted of five parts: the evolution of the forming force, main geometrical parameters, failure modes, static strength, and absorbed energy. The results show that five parameters can be employed to assess the joining reliability, where the neck thickness of the first interlock and the interlock width of the second interlock perform essential roles in the static strength and failure modes of the joint. In the static strength tests, the joint sample, in which the bottom sheet is clamped on its own while the middle and upper sheets are clamped together, exhibits higher static strength and absorbed energy than the joint sample where the upper sheet is clamped on its own while the middle and bottom sheets are clamped together. In addition, the joint specimens with different sheet configurations have different failure modes. The flat-clinching can join three-layer sheets by two interlocks to create a thin-walled structure.
Highlights Flat-clinching process can be used to join three-layers sheets by two interlocks. The neck thickness of first interlock and the interlock width of second interlock significantly affect the joining strength. FC-2 joint samples exhibit higher static strengths than FC-1 joint samples. The joint specimens with different sheet configurations have different failure modes.
