The integral term represents aerodynamic memory (e.g., from wake vorticity). For subsonic compressible flow, the provides (\mathbfQ(k)) in the frequency domain. 3. Static Aeroelasticity: Divergence Setting inertia and damping to zero leads to static equilibrium: [ \left[ -\omega^2 \mathbfM + i\omega \mathbfC +

typically uses a loose staggering with sub-iterations: \textdiv = 1 / \lambda_\min). Physically

Divergence occurs when the smallest eigenvalue (\lambda_\min) of (\mathbfK^-1 \mathbfA 0) satisfies (q \infty, \textdiv = 1 / \lambda_\min). Physically, aerodynamic moments overcome structural stiffness. Assume harmonic motion (\mathbfu = \hat\mathbfu e^i\omega t) and use frequency-domain aerodynamics (\mathbfQ(i\omega)):
