Abstract
The object of the present paper is the dynamic analysis of plane structures with FLD viscoelastic layers. This study has been performed by utilizing a FEM code (Viscoplate) and a hybrid element developed for this aim. In particular partial damping treatments have been considered and compared each other in terms of damping performances. Different viscoelastic distributions have been analyzed in order to evaluate how the patch design may influence the damping performances of the coupled structure. Damping parameters have been obtained by means of the traditional Modal Strain Energy (MSE) method and by two new modified versions (new modified MSE and corrected MSE).Pubblicazioni consigliate
