This study considers the scattering of compressional and shear waves in SiC-particle-reinforced Al composite with interfacial layers. We assume same-size inclusions and same-thickness layers with nonhomogeneous elastic properties. The effective complex wave numbers follow from the coherent wave equations which depend only upon the scattering amplitude of the single scattering problem. Numerical values of scattering cross-sections, and phase velocities and attenuations of coherent plane waves are obtained for a moderately wide range of frequencies, and the results are graphed to display the effects of concentration of scatterers and interface properties.
