In this paper an investigation is presented into the stability of skew plates acted upon by both aerodynamic and in-plane forces simultaneously. The in-plane force is assumed to be small in magnitude compared to the aerodynamic force. Due to this small in-plane force, the system may become unstable

β¦ Synopsis
The free vibration analysis for outer-clamped annular plates under arbitrary in-plane (self-equilibrating) force is formulated to investigate the influence of an in-plane force on the transverse vibration of the plates. The arbitrary in-plane force along the outer edge of an annular plate is expressed as a Fourier series, and perturbation and Galerkin methods are employed to obtain modal parameters. In particular, it is shown that the perturbation method not only reduces the computational effort but allows clear physical insight into the effect of uniform and non-uniform in-plane force on the modal parameters of an annular plate. Through numerical examples, both methods are compared and the effectiveness of the perturbation method is discussed.

This paper presents an investigation into the dynamic stability of skew plates acted upon simultaneously by an aerodynamic force in the chordwise direction and a random in-plane force in the spanwise direction. Due to this random in-plane force, the plate may become unstable before the aerodynamic f
