A model for a moderately deep underwater explosion bubble is developed that integrates the shock wave and oscillation phases of motion. hyperacoustic relationship formulated relates volume acceleration to far-field pressure profile during shock-wave phase, thereby providing initial conditions subsequent phase. For latter, equations bubble-surface response are derived include effects in both external liquid internal gas. The then specialized case spherical bubble, displacement histories calculated dilational translational Agreement between these experimental data found be substantially better than produced by previous models.
