Finite Element Analysis for Mechanical Characteristics of Resistance Spot Welding Process with Three Sheets Assemblies

This project is focused on the finite element (FE) analysis for mechanical characteristics of resistance spot welding (RSW) process with three sheets stack up instead of conventional two sheets assemblies because of its wide application in automobile industry. It is proved that the protuberances region localized in the nugget area induced in the welding process are more inclined to have fatigue failure such as cracks and fracture. Local stress...
