coating modeling

Dr.CW Wu

I am working on my M.s.a thesis about Numerical simulation of fatigue strenght of resistance spot welding joints of coated thin.At first I need to model a  steel palte with three different coating on it and apply a thermal analysis to achive to residual stress distribution.I couldent find any journal or paper in this field and dont know  from where i should exactly start my simulation in ANSYS.can you help me? 

Thanks
