“…On the other hand, Neugebauer et al 31 completed the mechanical joining of magnesium structures using a flat clinching process. In the works of Chen et al, [32][33][34][35] the effect of diverse plate materials and diverse plate configurations on the mechanical characteristics of flat clinched joints was investigated. These results showed that the flat clinching process was benefit to forming the flat clinched joints without extra protrusion.…”

Polyoxymethylene (POM), as an energy‐saving material, is widely applied in the manufacturing field. Yet, research on the rectangular clinching process between metal and POM sheets is still lacking. In this paper, the rectangular clinching process for POM and Al5052‐H32 plates was investigated. The feasibility of the metal–polymer hybrid component had been analyzed in terms of diverse forming forces and diverse joint layout angles, respectively. The mechanical characteristics were appraised by the lap‐shear test. The failure modes of rectangular clinched joints produced under diverse forming conditions had also been analyzed. The results showed that the optimal forming force of rectangular clinched joints was 14 kN, in which the lap‐shear strength was 1090 N. Furthermore, the rectangular clinched joints produced under the joint layout angle of 90° could withstand the maximum lap‐shear load (1415 N) under the optimal forming force. The failure mode was the separation of two plates and the fracture of the bridge structures.

“…Furthermore, it is not suitable for joining thin sheets with low ductility and high hardness since the self-piercing riveting technology needs to penetrate the connected plates. A special adhesive is used to join the sheet materials in the adhesive bonding technology [10][11][12][13][14]. The adhesive bonding technology can join various sheet materials.…”

Clinching technology can join thin sheets of various materials, including aluminum alloy, magnesium alloy, steel, titanium alloy, and polymers. Nowadays, with the popularization of the lightweight concept and the application of various sheet materials in manufacturing, clinching technology has highlighted the advantages of being able to adapt to the joining of different sheet materials. With its unique advantages, clinching technology gains wide development space in the field of metal sheet connection. The application of clinching technology in various sheet materials is summarized and analyzed. The clinching process of special materials is also discussed. In addition, some unaddressed issues in the clinching process of special materials are identified in this paper.

“…In recent years, the high convexity of clinched joints limits the application of mechanical clinching technology. Chen et al 1,[23][24][25][26][27][28][29][30] proposed a method of reshaping to reduce the protruding height of clinched joints. They also analyzed the influence of different parameters on the neck thickness and undercut.…”

The clinching process is more and more used in automotive design and manufacturing. Traditional quality inspection of joints needs a lot of destructive tests, which is time-consuming and material-consuming. In this paper, the clinching process and joints failure of dissimilar materials, 6061 aluminium alloy and HC340/590DP dual-phase steel, are studied. A two-dimensional finite element model is established. Experiments were carried out to verify the numerical model. Through the axial tensile test, the quality of clinched joints for upper steel-lower aluminium alloy and upper aluminium alloy-lower steel were measured, respectively, and the strength and safety of the joints met the requirements of design indexes. The conventional prediction model of maximum tensile force and its modified model was researched. Combined with numerical simulation results, the fracture load, the separation load, and the failure mode of two clinched joints were predicted, respectively. Furthermore, the results are in good agreement with the experimental results. The results show that the modified prediction model of maximum tensile force has a good prediction result, and the error rate is less than 10%. The modified prediction model of maximum tensile force can effectively predict the tensile failure test results, which provides a basis for the quality evaluation and strength prediction optimization of dissimilar materials clinched joints.
