This paper is dedicated to investigate the nonlinear free vibration analysis of prestressed orthotropic membranes. The fundamental frequency of the system is obtained asymptotically by employing a modern analytical approach. The effects of different parameters such as vibration amplitude, initial conditions and geometric parameters on the frequency ratio and nonlinear frequency of membrane are investigated. Comparison between the obtained results in the present study, the reported results in the literature, and Runge-Kutta fourth-order numerical method verify the strength of the analytical procedure.
