“…Extensible dies allow adapting the die cavity to the material flow during the clinching process [30]. As a result, a minor hydrostatic stress is produced requiring lower forming force [31]. In addition, extensible dies allow producing larger interlocks as compared to grooved dies other than producing more flat protrusions with significant improvement from an aesthetical point of view [32].…”

“…In addition, higher forming forces produce larger interlocks without affecting significantly the neck thickness [18,31,21]. Finally, according to some experimental finding achieved in preliminary tests, the neck thickness resulted higher than the interlock; thus, in the experimental campaign, the maximum available joining force (F j =22 kN) was adopted.…”

The joinability of different rigid thermoplastic polymers with aluminium AA6082-T6 alloy sheets by mechanical clinching is investigated. The polymers were heated using a convective source prior of clinching. Experimental tests were conducted by varying die geometry and preheating time. The joinability window for different thermoplastic polymers including polystyrene (PS), polycarbonate (PC) and poly(methyl methacrylate) (PMMA) was determined. The mechanical behaviours of clinched connections were assessed by means of single lap shear tests. To understand the effect of process parameters on the mechanical behaviours of clinched joints, dimensional analysis was also carried out. It was turned out that mechanical clinching could be successfully employed for joining thermoplastic polymer sheets with aluminium sheets being characterized by a very short processing time and producing high strength joints as compared to competitive technologies. The formability of the aluminium alloy and the toughness of the polymer component are crucial for the success of the process. However, even materials with reduced formability were joined by modifying conveniently the preheating time and die geometry.

“…Therefore, the threshold value of the joining force (below which the interlock is not formed) was investigated. Actually, other than depending on the materials flow stress and thickness of the sheets, the joining force threshold is highly influenced by the clinching tools configuration and mainly by the developing hydrostatic stress [31]. The second possible failure condition experienced while joining the analysed materials with split dies was the shearing of the metal button (see Fig.…”

“…In order to deal with new types of materials as well to achieve the best mechanical performance either reduce the joining force, different types of tools have been developed in the recent years including rectangular, round grooved, round flat and round split dies. Lambiase and Di Ilio [31] compared the mechanical performances of clinched connections (on mild steel sheets) performed with round grooved and round split dies. The research turned out that, extensible dies allow reducing the joining force and increase the mechanical behaviour of clinched connections.…”

“…Lambiase and Di Ilio [59] conducted an experimental investigation to assess the main differences among clinched joints produced with different die configurations, including an extensible die and three different fixed dies. The samples were joined with different forming forces and were analyzed by means of different mechanical tests, including lap shear tests, with one and two joints, and peeling tests.…”

Clinching is a mechanical joining method using a simple toolset consisting of a punch, a die, and a blank holder. The shapes of these tools are the most important parameters that control the final geometry of the clinch joints and consequently the strength and quality of the latter. In order to save time and cost, these geometric parameters could be optimized by the use of finite element simulation. This paper reviews the published research related to the finite element modeling of the clinching process. In this study, a critical review of the latter had been carried out from different perspectives. The findings about difficulties facing the simulations of different clinching processes, the optimization of the process parameters, and the strength, joinability, and the quality of the joint were highlighted. In addition, future development, investigation, and more research are still needed to minimize problems and expenses in the industrial practical application of clinching.
