- Abstract
The present paper presents in an informative manner, an efficient method providing the dispersion curves for a planar multilayered structure in vacuum, made of isotropic homogeneous visco-elastic materials. The energy flux of the resulting generalized Lamb waves is then determined for each frequency in the selected range. The energy flux distribution, as function of the position along the normal direction on the laminar structure, can thus be plotted. The flux integral along the cross-section is obtained and represented as function of frequency for all propagating modes.
