Using Reddy's higher order shear deformation plate theory, the #ow-induced vibrations of simply supported shear-deformable laminated plates exposed to an oscillating #ow are studied. The plate is assumed to be placed normal to the #ow. The #uid}structure interaction is based on Morison's model, which leads to a non-linear motion equation. The state variable approach is used in conjunction with the Spline collocation method to determine the dynamic response of the plate. Numerical illustrations concern the dynamic response of antisymmetric angle-ply and symmetric cross-ply laminated plates under oscillating #ow. The roles played by plate aspect ratio, total number of plies, "ber orientation, as well as transverse shear deformation are studied. In all cases, non-linear e!ects lead to rather complex vibrations and to essentially chaotic motion.
