This paper investigates the effect of structural, electrical and thermal coupled field phenomena on electric contact used in the electric switches. An axis symmetric two dimensional elastic-plastic finite element (FE) model for sphere and plane is developed to predict the contact behavior with smooth surface. Structural analysis of finite element analysis is performed and the FE model is coupled with electric-thermal analysis model through COMSOL multi-physics software. The model is simulated with different boundary conditions and contact area to analyze the temperature fall at the point of contact. Electro-thermo-mechanical coupled field simulation is carried for alternative current (AC) with frequency of 50 Hz. The comparison between analytical and numerical results is to predict the behavior of electric contacts for two different types of currents DC and AC which is used in electric switches. © 2016 IEEE.
