Abstract—In this study, a thin aluminum sheet are to be joined by mechanical clinching. The diameter of the die and stroke of the punch are controlled whereas the thickness of the sheets, diameter of the punch and speed of the machine are fixed in order to obtain the best results. It was found that mechanical clinching has superior fatigue strength due to the large yield stress of the sheets and relaxation of the stress concentration. The interlocking between the sheets, the thinning of the sheet and the fracture were observed.
Index Terms—Mechanical clinching, plastics deformation, fracture, joining.
