Zhang, P. (author), Li, S. (author), Nunez, Alfredo (author), Li, Z. (author)In this paper, we present a solution method based on finite element (FE) modeling to predict multimodal dispersive waves in a free rail. As well as the modal behaviors and wavenumber-frequency dispersion relations, the phase and group velocities of six types of propagative waves are also derived and discussed in detail in the frequency range...journal article 2021
