Abstract: In the present paper,the vibration of an initially deflected rectangular plate under sinusoidally time-varying inplane momentis examined from the point of view of dynamic instability. The equation of motion describing the large deflection of the initially deflected plate is analyzed by the Galerkin method. The resulting equations for time variables are integrated by using the Runge-Kutta-Gill method. The dynamic instability regions are analysed by the small deflection theory by neglecting nonlinear terms. The amplitudes of unstable regions are determined by large deflection theory. Numerical results are presented for various initial deflection shapes and magnitudes. The relation between the initial deflection and dynamic instability is discussed.
