Much current practical interest exists concerning wave propagation through a composite medium with a random distribution of inclusions particles, flakes, long continuous or chopped fibers in a homogeneous matrix. Several theoretical studies report wave speeds and attenuation of coherent plane waves propagating through an elastic homogeneous medium containing reinforcing particles or fibers. All theses studies assume that the interface between the matrix and the inclusion is sharply defined. Also, it is mostly assumed that the inclusion is perfectly bonded to the matrix. The present study, analyzes the problem of damping in metal-matrix composites when there is an interface layer through which the inclusion property changes continuously to that of the matrix.
