A finite-element approach has been developed for determining nonlinear flutter characteristics of two-dimensional panels, based on aerodynamic forces from quasi-steady aerodynamic theory. The stiffness equations of motion, iterative solution procedure, and convergence characteristics are presented. Comparisons are made with linear flutter and large amplitude vibration results and demonstrate that good accuracy is obtained. Nonlinear flutter results are presented; effects of aerodynamic damping, boundary support conditions, and initial in-plane forces are included.
