“…Zhou et al [16] predicted the transient response and wave behavior for piezoelectric cylindrical shells. Yu et al investigated the guided waves in laminated cylindrical shells with sectorial crosssection subjected to initial stress [17] and thermoelastic waves in hollow cylinders [18], and both solutions were analytical. Li et al [19] presented the wave propagation analysis of graphene-reinforced piezoelectric polymer cylindrical shells based on FSDT.…”

Based on the first-order shear deformation theory (FSDT) and Kelvin–Voigt viscoelastic model, one derives a wave equation of longitudinal guide waves in viscoelastic orthotropic cylindrical shells, which analytically solves the wave equation and explains the intrinsic meaning of the wave propagation. In the numerical examples, the velocity curves of the first few modes for the elastic cylindrical shell are first calculated, and the results of the available literature are compared to verify the derivation and programming. Furthermore, the phase velocity curves and attenuation coefficient curves of the guide waves for a functionally graded (FG) shell are calculated, and the effects of viscoelastic parameters, material gradient patterns, material volume fractions, and size ratios on the phase velocity curves and attenuation curves are studied. This study can be widely used to analytically model the wave propagating in inhomogeneous viscoelastic composite structures and present a theoretical basis for the excellent service performance of composite structures and ultrasonic devices.

“…Viktorov firstly discovered that the guided wave propagating in either a convex or a concave shell is different from that in a flat plate, and defined the angular wavenumber [26]. Later, some studies provided theoretical results for such waveguides [27][28][29][30]. However, it is hard to find relevant experiments of the circumferential interface wave in a multi-layered structure.…”

This paper focuses on the dispersion characteristic of interface waves and the detection of interlaminar defects in multilayered pipes. The interface waves propagating along axial and circumferential directions are simplified as strain problems of planes (r, z) and (r, θ), respectively. The axial interface wave is well suited to axial localization of the defect, just as the circumferential interface wave is to circumferential localization. The dispersion curves and wave structures in generalized forms are built based on double- and treble-layered examples. Both interface waves converge to the Stoneley wave velocity at high frequency, while energy is concentrated on the interface. An experimental system is built. Theoretical and experimental group velocities are compared. The results indicate that the average relative errors of these two interface waves are 0.47% and 0.53%, respectively. An interlaminar crack is detected effectively both in axial and circumferential directions, revealing that interface waves hold great potential for non-destructive evaluation.
