Vibration and acoustic response of damped sandwich plates immersed in a light or heavy fluid
چکیده انگلیسی

This paper presents a finite element formulation to analyze the vibro-acoustic response of plates with constrained-layer damping treatment. This formulation takes into account the effects of fluid loading. The governing coupled structural/acoustic equations of motion are solved using a modal approach combined with an interpolation technique of the reduced radiation impedance matrix components of the fluid. The numerical results show the accuracy of the proposed approach. In addition, a parametric study is carried out to highlight the influence of geometrical and material variables on the damping characteristics, which could be used as design parameters for the optimization problem.
