✦ Synopsis

This paper presents di!erential quadrature solutions for free vibration analysis of moderately thick annular sector plates based on the Mindlin "rst-order shear deformation theory. Numerical characteristics of the di!erential quadrature method are illustrated through solving selected annular sector plates with di!erent boundary conditions, relative thickness ratios, inner-to-outer radius ratios and various sector angles. Parametric studies in terms of the vibration frequency parameters are thoroughly investigated.

In this paper, the two-dimensional di!erential quadrature element method (DQEM) is developed for the static analysis of symmetric cross-ply laminates using the "rst-order shear deformation plate theory. In this study, the laminated plate, which may contain di!erent discontinuities in loading, geomet

Axisymmetric free vibrations of moderately thick circular plates described by the linear shear-deformation Mindlin theory are analyzed by the differential quadrature (DQ) method. The first fifteen natural frequencies of vibration are calculated for uniform circular plates with free, simply-supported
