    Abstract: Results are reported on damping effectiveness during flexural vibrations of multi-layered beams, with constrained viscoelastic layers. These are given for simply supported beams with number of layers up to 15, all viscoelastic layers being identical. The elastic layers are also taken to be similar to one another. The influence of number of layers and thickness ratio of viscoelastic to elastic layers, for constant size, constant weight and constant static stiffness criteria, has been studied. In order to obtain maximum value of loss factor or of displacement response effectiveness for multilayered beams, under specific requirements of static stiffness, weight and size, a suitable choice of number of layers and thickness ratio of viscoelastic to elastic layers, is found to be important.
