“…In [30] the influence of strain hardening and the variation of sheet thickness on the joint characteristics t n , f and t b are studied using a metamodel to investigate the robustness of the clinching process. In [31] the possibilities and limitations of FEM-based sensitivity analysis and optimization for the clinching process are discussed. For the optimization of the clinching tools, the sensitivities of the most important tool dimensions and a robustness analysis are determined.…”

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.

“…When using the clinching process to connect sheets with different strengths and plasticity, the sheets' position relative to the arrangement of the die is fundamental. The potential and limitation of sensitivity analysis and optimization of forming process connection based on the finite element method have been discussed through examples [70]. Tools for specific material combinations and those for connecting different thicknesses and plates were designed.…”

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.

“…Experimental evidence confirmed the validity of their approach. The potential use of FE-based methods for conducting sensitivity analysis and optimization studies for clinch joining was presented by Drossel et al [ 146 ]. The authors derived the most important values for forming die optimization by determining the sensitivity of the design to variations in the connection parameters.…”
