ANALYTICAL INVESTIGATION OF THE DAMPING CAPABILITY OF LAMINATED BEAMS.
Abstract
The free and forced vibration of a three-layer, elastic-viscoelastic- elastic, beam are investigated. The results of previous studies are extended to obtain the boundary-condition equation for free and forced vibrations. These are written explicitly. Detailed results are obtained for the sandwich beam having a thin viscoelastic layer. Generalized results are obtained for the composite loss-factor and are plotted for use by a design engineer. Curves are available which simplify the determination of the natural frequencies and the associated mode shapes, and which aid in the calculation of the forced response. (Author)
