Free vibration of moderately thick antisymmetric laminated annular sector plates with elastic edge constraints

• Free vibration results of laminated sector plates having elastic edges.
• Continuous variation of edge stiffnesses simulate the complete range of classical boundary conditions.
• Differential quadrature method used for spatial discretization.

This study presents, for the first time, free vibration results of laminated sector plates having elastic edges. Each layer is cylindrically orthotropic. A differential quadrature method (DQM) based formulation is used for studying the problem of shear-deformable laminated sector plates having translational as well as rotational edge constraints. By varying the edge stiffnesses, several combinations of simply supported and clamped edge conditions are simulated. The results are further validated by comparison with the results of laminated square plates (with elastic edges) and of laminated sector plates (without elastic edges) available in the literature.
