TRANSVERSE ELASTIC WAVES IN AN INTERNAL STRATUM
( (College of Science and Technology Manchester) )
This paper is concerned with the propagation of Love waves in a stratum bounded by infinite media with different elastic properties. The symmetrical case is considered first and it is shown that there are an infinite number of modes of vibration. The properties of the dispersion curves in each mode are derived. These properties are illustrated by graphs obtained from numerical computation. It is found that the general case is very similar to the case of symmetry, and corresponding results are given. The limits between which the phase and group velocities must lie are fousnd in each case, and cut-off frequencies and wavelengths are also determined for each mode.
