Abstract

An incrementally coupled finite element modeling approach to deal with electrical-thermal-mechanical coupling effects in resistance spot welding is described. The interactions between the electrical-thermal analysis and the thermal-mechanical analysis are solved in an incremental way. A phenomenological contact resistance model is proposed to define the contact resistance as a function of temperature, contact pressure and material yield strength. It is found that the initial contact area at the faying surface is strongly dependent upon the sheet metal thickness, the electrode face geometry and to the applied force level.
