The use of Rayleigh waves enables the solution of several important inspection problems. Propagation ofsurface waves along straight boundaries has been properly studied but investigations about their propagation on cylindrical surfaces are not sufﬁcient, despite they can be still of interest for NDE applications.It has been proved experimentally that a surface wave pulse suffers a phase shift during its propagationalong a cylindrical surface. A numerical approach has been developed to efﬁciently study these effects fordifferent materials, curvatures and frequencies. This study can help the scientiﬁc community to betterunderstand the phenomenon, quite complex and not yet fully explored.
