Wave reflection from the free end of a cylinder with an arbitrary cross-section
TL;DR: In this paper, the wave scattering at the free end of a cylinder due to an incident monochromatic wave is investigated, and the amplitude of the traveling waves and end modes that satisfy traction-free end conditions are determined by least squares minimization or by a virtual work method.

Elastic guided waves in a layered plate with rectangular cross section.
TL;DR: A semianalytical finite element method in which the deformation of the cross section is modeled by two-dimensional finite elements and analytical representation of propagating waves along the length of the plate has been used to study guided waves in a layered elastic plate of rectangular cross section.

Energy concentration at the center of large aspect ratio rectangular waveguides at high frequencies
TL;DR: Wave propagation in infinitely long strips of large rectangular aspect ratio is discussed and two guided wave modes of a large aspect ratio rectangular strip whose dispersion characteristics approach those of the fundamental modes of an infinitely wide plate at high frequencies are shown.

Surface wave modes in rails
D. Hesse,Peter Cawley +1 more
TL;DR: In this article, the dispersion curves of the dominant surface wave modes were determined up to a frequency of 350kHz using a finite element model and show excellent agreement with experimental data, and one surface wave mode was identified to be nondispersive and not significantly affected by cross-section changes due to wear at frequencies above 180kHz.
