An approximate analytical solution is presented for free vibration of a symmetrically laminated curved panel with simply supported (SS2), clamped (CC2), as well as mixed simply supported and clamped boundary conditions. The coupled partial differential equations with associated boundary conditions to first-order shear deformation theory are solved by using modified Galerkin method; vibration fequencies and mode shapes are determined. Effects of the boundary conditions, thickness ratio a/h, curvature, R/h, and lamination angle, θ, on the vibration frequency are discussed.
