Flutter Speed Limits of Cantilever Rectangular and Tapered Plates

Al-Khawarizmi Engineering Journal, 2007
The aerodynamic and elastic forces may cause an oscillation of the structure such as the high frequency of the airfoil surfaces and the dynamic instability occurring in an aircraft in flight and failure may occur at a speed called flutter speed.
