Abstract : Presented herein is a user's manual for the ELSHOK computer code. This computer program calculates the transient response of a submerged ring-stiffened shell of revolution, with or without internal structure, to an underwater shock wave having an arbitrary direction of impingement. Linearly elastic structures are considered, and the surrounding fluid is treated as an infinite acoustic medium. Modal analysis is employed for the structure, while the analysis of the fluid is based upon the Doubly Asymptotic Approximation. (Author)
