The Propagation at Short Ranges of Elastic Waves from an Impulsive Source at a Liquid-Solid Interface - The Fluid-Two Layer Solid System
Abstract
An extension is presented to a system of a fluid layer and two underlying solid layers, of a theory recently published by Strick which concerns the prediction of the pressure field produced at short ranges by an impulsive sound source near a fluid-homogeneous solid interface. The theoretical extension should prove useful in permitting the prediction of the pressure field at close ranges produced by a low-frequency sound source lying near the ocean floor. Although the final form of the extended theory is not ob tained in closed form, it can predict all arrivals at short ranges. It is concluded that the existence of Stoneley waves at a solid-solid interface is unlikely, although reflections from the solid-solid interface may be responsible for the formation of additional Stoneley waves at the fluid-solid interface.
