Abstract : The extension made by Spitznogle to include a complex air-fluid two-layer elastic solid system in Strick's theory of the propagation of elastic waves from an impulsive source along a fluid-solid interfaces has been further expanded. In the previous work the source-function considered was a single impulse. This has been replaced (in the present work) by a source-function which is a series of such impulses. Theoretical waveforms are computed for an air-water-glass-aluminum model and various impulsive source-functions ranging from the single impulse to a sequence of impulese of various magnitudes and spacings in time.
