In this paper, the iterative decomposition method is applied to solve the system of nonlinear differential equation arising from Nano Electromechanical Switches (NEMS) modeling. Two types of nano-beam actuators contain cantilever and double cantilever are considered and the effects of Casimir and Vander Waals forces on the deflection of micro- and nano-beam actuators are investigated numerically. The pull-in instability parameters of the switch have been considered and compared with those of numerical solution. It is found that using conventional decomposition method in solving NEMS problems can lead to physically incorrect results. The numerical results for different cases of beam are presented and compared in order to demonstrate the accuracy and capability of the proposed method.
