|Free asymmetric transverse vibration of polar orthotropic annular sector plate with linearly varying thickness in the radial direction
|Singh, R P
Jain, S K
|In the present paper, free asymmetric transverse vibration of a non-uniform polar orthotropic annular sector plate with a linearly varying thickness in the radial direction have been studied on the basis of classical plate theory when the circular edges of the plate are elastically restrained against translation and rotation while straight (radial) edges are simply-supported. The fourth order linear differential equations with variable coefficients governing the motion have been solved by using collocation technique with Chebyshev collocation points as the interpolating nodes. Frequency parameters of the plate with flexible boundary conditions at the circular edges for some typical values of the taper parameters, the rigidity ratios and the radii ratio have been presented.
