Scattering of Antiplane Shear Waves in a Piezoelectric Fibrous Composite Medium with Slip at Interfaces

This study considers the phase velocity and attenuation of time harmonic axial shear waves in a piezoelectric fibrous composite with slip at interfaces subjected to a steady-state in-plane electrical load. Scattering of plane axial shear waves by a circular piezoelectric fiber with slip is analyzed. We apply the results of the single scattering problem to the propagation of any desired finite frequency waves in a composite containing a dilute concentration of circular piezoelectric fibers. Numerical results for some piezoelectric fibrous composites are obtained and the effects of interfacial slippages and electroelastic interactions on the phase velocity and attenuation of coherent plane waves are discussed in detail.
