On the Coupling of Guided Cylindrical Waves in Thick-Walled Structures
Résumé
In this study, systematic analysis of the wave propagation characteristics in a thick-walled cylindrical structure was achieved with a purpose of facilitating the development of a damage detection system for train axles. The correspondence of thick hollow cylinder waves to the plate wave solutions of symmetric and antisymmetric modes, and the influence of thickness and radius on wave propagation were examined through the asymptotic approximations of Bessel functions. The analytical solutions to dispersion characteristics were compared with numerical simulations using the Local Interaction Simulation Approach and experimental validation.
