Abstract

Energy absorbing composite joints can be effective in noise and vibration suppression of marine and aerospace structures. The vibration suppression in a typical Top-Hat stiffener structural joint, with viscoelastic insert is presented in this paper. Using FEM modeling, the damping performance of this composite joint is predicted. Experiments are carried out to validate the numerical analysis.
