A Review of Finite Element Analysis (FEA) of Resistance Spot Welding (RSW) Metoda analizy elementów skończonych (FEA) w zastosowaniu do zgrzewania rezystancyjnego punktowego (RSW)

Modeling RSW was studied by many researchers with considering different electrical, thermal, and mechanical phenomena such as formation of temperature �耀eld and welding nugget growth. This paper is a review of the most important efforts in the �耀eld of FEA of RSW, by investigating present �耀nite element method (FEM) studies. After a brief introduction on FEA studies on RSW, such numerical solution methods as FEM and FDM (Finite Difference Method) are compared. Governing electrical, thermal, and mechanical equations are then discussed. A brief investigation about applicable algorithms is presented as a procedure for numerical solution. The importance of credible material properties is emphasized and predicted results in different studies are discussed. The �耀nal two parts are about recent issues in RSW FEA process and review of special cases such as multiple-sheet, single-sided welding, shunting effect, and covered models. Conclusions and suggestions about future studies are also provided.
