Abstract

An improved dynamical model for vibration damping in composite structures is introduced to incorporate the code number and the degree of isotropism against the modal parameters. A substantial development has been carried out from the fitting of modal measurements with lowest residual errors to permit an establishment of quasi uniform mass damping models in terms of normal coordinates system. The analysis of the obtained results proves not only the efficiency of the developed model but also its applicability in any wide range of frequency spectrum of composites.
