Modeling of vibration damping in composite structures

An improved dynamical model for vibration damping in composite structures i s introduced to investigate the stacking sequence and the degree of anisotr opy as a function of the vibration modes. Extensive investigation has been carried out from the fitting of modal measurements with lowest residual err ors to establish quasi-uniform mass damping models in terms of normal coord inates system. The analysis of the obtained results proves not only the eff iciency of the proposed model but also its applicability in any wide range of frequency spectrum of composites.
