Fundamental mechanisms and their interactions in shear‐clinching technology and investigation of the process robustness

Abstract

was das Fügen artungleicher Werkstoffe mit stark unterschiedlichen mechanischen Eigenschaften ermöglicht. Aus der Kombination der Teilprozesse Schneiden und Fügen ergibt sich eine erhöhte Komplexität. Innerhalb der vorliegenden Arbeit werden daher grundlegende Mechanismen beim Schneidclinchen und deren Wechselwirkung sowie die Robustheit des Prozesses untersucht, um die Anwendbarkeit der Technologie zu verbessern.

The State of the Art of Finite Element Analysis in Mechanical Clinching

“…With the development of clinching technology, the concept of clinching connection technology is constantly expanding. Based on this technology, hole-clinching [7][8][9], shear-clinching [10][11][12][13][14][15][16], friction-stir clinching [17][18][19][20][21], clinching-welding technology [22][23][24], and clinch-bond composite technology [25,26] have been developed and applied. The materials have been extended from carbon steel and aluminum alloy to new types of refractory materials such as high-strength steel [27][28][29][30][31][32][33], titanium alloy, and magnesium alloy, which present special advantages in the connection between a metal and a non-metal (carbon fiber and polymer [34][35][36][37][38][39][40][41][42][43][44][45][46]).…”

Experimental investigation of Al5052‐H32/PETG hybrid clinched joints

“…In brief, except for the four types of dies mentioned above, some novel techniques have been innovated and developed by many scholars, such as hole-clinching, [31][32][33] shear clinching, [34][35][36] and laser shock hole-clinching. 37,38 Meanwhile, the reshaping method is also proposed to enhance the strength of clinched joints.…”
