The propagation at short ranges of elastic waves from an impulsive source at a liquid solid interface - fluid-solid model
An investigation of the propagation of an impul sive sound front near a model ocean floor at very near ranges is presented. Prior theoretical endeavors in the field are analyzed and a recent theory by E. Strick on the subject is considered in detail. The theory advanced by Strick is the first practical theory that can treat the ocean floor as a rigid solid (instead of a liquid) and still be valid at ranges of a few wave lengths or less. Experimental data is presented for model ranges varying from 0.2 mean wave lengths to 2.0 mean wavelengths, and theoretical comparisons attest to the validity of the theory at such ranges. It is believed that this theory will prove useful in predicting the pressure response at the ocean floor near an impulsive or explosive sound source. (Author)
