Large deflections of a structurally damped panel in a subsonic flow

摘要: The large deflections of panels in subsonic flow are considered, specifically a fully clamped von Karman plate accounting for both rotational inertia filaments and (mild) structural damping. panel is taken to be embedded the boundary positive half-space $$\mathbb R^3$$ containing linear, potential flow. Solutions constructed via semigroup approach despite lack natural dissipativity associated with generator linear dynamics. flow–plate dynamics then reduced—via an explicit Neumann-to-Dirichlet (downwash-to-pressure) solver flow—to memory-type dynamical system plate. For non-conservative dynamics, global attractor explicitly Lyapunov recent quasi-stability methods. Finally, it shown that, compactness finiteness dissipation integral, all trajectories converge strongly set stationary states.
