Free vibration of transverse isotropic annular sector mindlin plates

The natural frequencies of moderately thick transverse isotropic annular sector plates, as obtained by using Mindlin's theory, which includes the effect of shear deformation and rotatory inertia, are presented. The plate is clamped at all the edges. An integral equation technique has been used in the analysis. The typical results are compared with those of other investigators who have used different methods for the solution. Numerical results have been obtained for different cases by varying the transverse shear modulus, sector angle and radii ratio. © 1985, Academic Press Inc. (London) Limited. All rights reserved.
