TLDR
In this article, a detailed investigation of the cylinder frequency equation is in order in the sizing process for bolt and pump-shaft inspections, and the wave scattering at the circumferential crack can be formulated in terms of the guided cylindrical waves which mathematically result from the cylinder frequencies equation.Abstract:
The propagation of a longitudinal wave in an isotropic cylinder has been used in the inspections of pumps and shafts of a nuclear power plant [1]. An ultrasonic technique called the “cylindrically guided wave technique” (CGWT) has been developed that can detect simulated circumferential defects through long metal paths in metallic materials being used for bolts and studs [1]. In the recent development of the sizing process for the cylindrically guided wave technique, the wave scattering at the circumferential crack can be formulated in terms of the guided cylindrical waves which mathematically result from the cylinder frequency equation. Therefore, a detailed investigation of the cylinder frequency equation is in order in the sizing process for bolt and pump-shaft inspections.read more

Wave propagation in transversely isotropic cylinders
TL;DR: In this paper, a new mathematical model for the propagation of longitudinal guided waves in free transversely isotropic cylinders is developed, which uses three scalar potential functions to represent the three wave modes which can propagate inside the cylinder.

A comparative study of guided wave propagation in timber poles with isotropic and transversely isotropic material models
TL;DR: In this paper, a comparative study of guided wave propagation in a timber pole is conducted considering isotropic and transversely-isotropic modeling, and the effect of temperature and moisture content (in terms of modulus of elasticity) in timber poles is also compared to show the variation in phase velocity.

The Seismological Implications of Aeolotropy in Continental Structure
TL;DR: In this article, it was shown that wave propagation over the surface of a transversely isotropic body in which the axis of circular symmetry is normal to the free surface, supposed plane, can be accomplished by Rayleigh wave propagation.
