Abstract:

This report constitutes a reference manual for the Underwater Shock Analysis USA Code, a computer program for calculation of the transient response of a submerged structure to a spherical shock wave of arbitrary pressure profile and source location. The code considers the structure to be linear-elastic and treats the surrounding fluid as an infinite acoustic medium. A discrete-element finite-element, finite-difference computational model is used for the structure, while the computational model for the fluid is based upon the Doubly Asymptotic Approximation.
