This paper presents differential quadrature solutions for free vibration analysis of moderately thick annular sector plates based on the Mindlin first-order shear deformation theory. Numerical characteristics of the differential quadrature method are illustrated through solving selected annular sector plates with different 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.
