An effective finite element method was used for the solution of aeroelastic model of cantilevered plates forced by aerodynamic loads in axial flow. A nonlinear equation of motion of plate based on the inextensibility assumption, coupled with an unsteady lumped vortex model for the aerodynamic part was used to analyze the dynamical behaviour of this fluid-structure system. The nonlinear partial differential equations of motion of the plate were discretized using the discontinuous Galerkin method. The resulting set of nonlinear ordinary differential equations for the plate was then solved by Houbolt´s finite difference method. Time traces, oscillation modes, locus of tip, PSDs, phase-plane plots, Poincaré maps, PDFs, and autocorrelations were used to characterize the motions of the system. Applications of this method to the fluid-structure interaction problems are presented and the results of the simulation illustrate the good performance.
