Abstract

Plane-wave propagation in a particle-reinforced composite medium with interfaces was studied for both compressional and shear incidences. The composite medium contains a random distribution of same sized spherical inclusions with elastic properties different from those of the matrix. The interface is assumed to be a thin layer of the same thickness with nonhomogeneous elastic properties which separates the inclusions from the matrix. The scattering of plane elastic waves by a spherical inclusion with an interface is analized and the results of the single scattering problem are applied to the wave propagation in the composite medium. Numerical solutions for some practical materials are carried out and the effect of interface properties on the scattering cross sections and attenuation coefficients of energy is shown graphically.
