✦ Synopsis

A previous work of the authors shows that a cantilever skew plate acted upon by an aerodynamic force and a small, slowly varying in-plane force may become unstable before the aerodynamic force reaches its critical value. This paper describes a study of the non-linear vibration of a cantilever skew plate when it becomes unstable. A finite element formulation is first applied to obtain the discretized system equations. The system equations are then partially uncoupled and reduced in size by the modal truncation method. Finally, the method of multiple scales is used to determine the response amplitudes of the plate. The effects of the system parameters on the response of the plate are studied numerically.

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

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
