| Abstract: | This work deals with the dispersion and attenuation of elastic plane waves propagating in a single layer fiber reinforced
composite, in a direction which is perpendicular to the fibers. An iterative effective medium model, based on single scattering
considerations, for the quantitative estimation of wave dispersion and attenuation is proposed. The single scattering problem
is solved numerically by means of a 2-D boundary element methodology. Numerical results concerning the plane velocity and
the attenuation coefficient of longitudinal or transverse SH, SV waves propagating in two types of fiber reinforced composite
materials, are presented. The obtained results are compared to those taken either experimentaly or numericaly by other investigators. |
