Description: Reported here are analytic formulations, together with one-dimensional results, in an investigation of the title subject. It is shown that either displacement or a displacement potential may be used as the basic dependent variable for a finite element analysis. Artificial damping is found to be needed to suppress spurious oscillations (a numerical phenomenon) near cavity boundaries. Adequacy of the method is demonstrated by comparison with published results of Bleich and Sandler. Some results are given for effects of cavitation on the performance of resilient attenuators.
