As a model problem of aeroelasticity the panel flutter problem is considered to study the discretization of nonlinear aeroelastic problems and the behaviour of the corresponding solution strategies. A fluid-structure discretization that mimics the energy budget of the continuous problem is derived.
A two-dimensional airfoil with either a bilinear or cubic structural nonlinearity in pitch, and subject to incompressible flow has been analysed; the aerodynamic forces on the airfoil are evaluated using Wagner's function. The resulting equations are either integrated numerically using a finite diff
