“…The extrapolation of the yield curve can be done e.g. with the Swift model [25], the Voce model [26], the Hollomon model [10] or the Cowper-Symonds model [27]. The Swift and Voce model are the most commonly used in the more recent publications.…”

Clinching is a joining process that is becoming more and more important in industry due to the increasing use of multi-material designs. Despite the already widespread use of the process, there is still a need for research to understand the mechanisms and design of clinched joints. In contrast to the tool parameters, process and material disturbances have not yet been investigated to a relatively large extent. However, these also have a great influence on the properties and applicability of clinching. The effect of process disturbances on the clinched joint are investigated with numerical and experimental methods. The investigated process variations are the history of the sheets using the pre-hardening of the material, different sheet thicknesses, sheet arrangements and punch strokes. For the consideration of the material history, a specimen geometry for pre-stretching specimens in uniaxial tension is used, from which the pre-stretched secondary specimens are taken. A finite element model is set up for the numerical investigations. Suitable clinching tools are selected. With the simulation, selected process influences can be examined. The effort of the numerical investigations is considerably reduced with the help of a statistical experimental design according to Taguchi. To confirm the simulation results, experimental investigations of the clinch point geometry by using micrographs and the shear strength of the clinched joint are performed. The analysis of the influence of difference disturbance factors on the clinching process demonstrate the importance of the holistic view of the clinching process.

“…The punch, the die, and the blank holder were defined as the rigid elements in LS-DYNA. Jagtap et al [56] reported performing a numerical simulation of the mechanical clinching process using fixed dies. The geometry of the clinching tools influences the strength and quality of the final clinch joint.…”

Clinching technology is a mechanical connection technology that is applied to connect metal or non-metal sheet materials. It is widely used in different applications, such as automobile, aircraft, household appliances and other industries. In order to reduce weight, save energy, reduce fuel consumption, reduce pollution and curb global warming, lightweight structures with clinched joint are increasingly used in transportation. The finite element technology is popularized in engineering, so that it can get similar results with the test after investing less time, manpower, energy and material resources, which is conducive to the prediction and smooth progress of the test. A review of the finite element analysis of clinching technology is provided in the present paper. The article's work also discusses the strength of the clinched joint, the factors influencing the clinched joint's strength, the failure mechanism of the clinched joint, etc. Furthermore, the novel technologies of clinching as well as the finite element models and methods used in clinching, are introduced. The present paper's main objective was to review the recent developments in the finite element analysis of clinching and provide a basis for further investigation in this area of research.

“…The stress due to the geometry of the clinching tools that causes material fractures was obtained [20]. Series simulations for the mechanical clinching to reveal the relation between the load and displacement were performed [21]. The simulations were validated comparing with an experimental study to obtain good mechanical interlock of two aluminum sheets.…”

The present paper deals with the numerical modeling and experimental testing of the clinched joint formed by DX51D + AZ150 and AISI 430 material pairs. The strength of the joint was determined experimentally by the tension and shear tests. The numerical model developed for the analysis was successfully validated with the experimental data. The strength of the joint formed by alternative material pairs such as H340LAD + AZ150 and DX52D + Z275 is investigated numerically. The clinched joints between the tumble endplates and flange bodies were done according to the main findings from the previous steps. The study focuses on the strength of the clinched joint as an alternative to flange connection in the case of using different tumble endplate materials. It is concluded that the clinched joint formed by AISI 430 tumble endplate has the highest strength. In the need for tumble capacity increase without changing the design, it is recommended to use AISI 430 material for tumble endplate and to consider strength values of AISI 430 material for capacity control. On the other hand, in case of using three different tumble endplates for the same die, punch and process conditions, the tumble capacity should be evaluated by considering DX52D + Z275 material which has the lowest strength.
