Abstract. Three-dimensional elasticity solutions have been presented for a thick laminated cross-ply
circular cylindrical panel. The cylindrical panel is under a dynamic localized patch moment, is simplysupported
at all edges and has nite length. Ordinary di erential equations with variable coecients are
formulated using an expansion of Fourier series applied to the displacement eld in circumferential and
axial direction. The resulting ordinary di erential equations are solved by the Galerkin nite element
method. Numerical results are presented for [0/90/0], [90/0/90], [0/90/0/90/0], [0/90/0/90/0/90/0]
and [0/90/0/90/0/90/0/90/0] stacking sequences.
