Construction of reduced order operators for hydroelastic vibrations of prestressed liquid–structure systems using separated parameters decomposition

This study deals with the computation of parameterized reduced order models for hydroelastic vibrations of interior fluid–structure systems with a free surface. The main parameter is the weight of the liquid acting on the structure, which allows static and dynamic simulations for different liquid he...
