Recent and future development of the application of finite element analysis in clinching process

Abstract

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.

Clinching for sheet materials

“…For obtaining optimal parameters combination subjected to multiple characteristics, Eshtayeh and Hrairi proposed a method of Taguchi-based Grey optimization in clinching [ 151,152 ]. LS-DYNA software was employed for evaluating the joint strength.…”

Experimental Investigation on the Joining of Aluminum Alloy Sheets Using Improved Clinching Process

“…The improved clinched joints were produced in the mechanical improved clinching process with different forming forces. The Al1060 sheets were hooked together by the mechanical interlock, thus the geometrical parameters are essential research contents in this study [ 51 ]. The improved clinched joint was cut by wire-cut electrical discharge machining technology along the center line of the joint to get the cross-sectional profile.…”

Investigation of the Restored Joint for Aluminum Alloy

“…With the development of lightweight structures, more and more light materials such as titanium alloy and aluminum alloy are utilized for building lightweight structures [1][2][3]. The joining of light materials is an important issue in the realm of joining technology [4].…”
