Phase velocity and attenuation of plane elastic waves in a particle-reinforced composite medium
This study considered effective-plane-wave propagation, both longitudinal and shear, through a medium containing a random distribution of spherical inclusions. It was assumed that the particles and matrix are separated by a thin layer of elastic material with different properties. For some systems, the authors predict measurable effects for the thin layers. Especially, they considered lead/epoxy and silicon carbide/aluminum. The object of this study was to explore the practicality of using ultrasound to characterize properties of interface layers. Ultrasound is a practical tool for measuring properties of, and characterizing the state of, a material with microstructure (or changes in microstructure).
