  abstract     = {{<p>This study investigates coupled reduced-order modeling to develop efficient methods for analyzing the vibro-acoustic response of geometrically nonlinear thin structures interacting with acoustic fluids, such as gas or liquid. Projection-based model reduction is adopted for the structural and fluid domain. To consider geometric nonlinearity, the reduced nonlinear restoring forces of the elastic structure are expressed as third order polynomials in modal coordinates. Consequently, the reduced system can be effectively solved using direct time-integration involving only the reduced coordinates. The study focuses on flat, thin structures where in-plane inertia effects can be neglected. For this specific case, the out-of-plane response can be represented by a set of bending modes, while the quasi-static in-plane response is considered implicitly. The proposed modeling strategy is validated by means of numerical examples investigating the vibro-acoustic response of thin panels interacting with acoustic cavities.</p>}},
