Abstract

Ultrasonic waves provide efficient means for the non-destructive characterization of composite materials. In the present paper, we study phase velocity and attenuation in a metal matrix composite reinforced by particles with interfacial layers. We assume same-size spherical inclusions and same-thickness interface 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 results are obtained for a moderately wide range of frequencies, and the effect of interface properties on phase velocities and attenuations of coherent plane waves is discussed in detail.
