PARAMETRIC INSTABILITY OF ROTATING CANTILEVER FUNCTIONALLY GRADED MATERIAL PLATES

Ramu Inala

Abstract :

 The present work deals with a finite element method for the viation and parametric instability of rotating cantilever FGM plates, based on first order shear deformation theory. The equation of motion of rotating FGM plates are established by using Hamilton’s principle and they are a set of coupled second order deferential Mathieu equation with periodic coefficients. The boundary parametric resonance frequencies of the motion are determined using Bolotin’s approach. The effect of power law index value, thickness ratio, radius of hub and rotating speed on dynamic stability of plates subjected to in–plane periodic loads are investigated using finite element method.  The excited frequency ratio of rotating FGM plates increase by increase the hub radius and rotational speed due to increase of overall stiffness for FGM plates. The overall enhancement of dynamic stability of the rotating cantilever FGM plates has been performed
