Abstract
Theoretical and numerical analyses of propagating properties of non-asymmetric flexural modes in a three-layered cylindrical transmission rod model are presented in this paper. The first order flexural mode and segments of the higher order flexural modes are behaving assemble to the Stoneley waves propagating along the inner and outer interfaces, respectively. Investigations of mode coupling between flexural and Stoneley modes assist to understand the exhibition and characteristics of the infinite number of separated Stoneley wave segments.
