Ultrasonic wave scattering from a single nano-fiber composite

The study of the interaction of ultrasonic waves with cylindrical structures has numerous applications including the ultrasonic nondestructive evaluation of materials. At nanoscale, surface and interface have significant effects on the physical and mechanical properties of solids, due to the increasing ratio of surface/interface area to volume. The scattering of a plane compressional wave by a cylindrical nano-fiber embedded in a solid matrix is investigated in this paper. To account for the effect of surface/interface energy at nanoscale, the surface/interface elasticity is incorporated in the analysis. The mathematical modeling shows that surface/interface parameter has significant effect on the scattering of elastic waves and the resonance modes when the radius of the inclusion decreases to nanometers.
