Numerical Analysis of the Elastic Shock Response of Submarine Installed Equipment

Abstract

Motivated by a lack of explosive test data on nuclear submarines, the Navy has sought other means to qualify installed equipment in submarine environments. The currently used method for non-shock testable items is the Dynamic Design Analysis Method (DDAM) developed by the Naval Research Laboratory in the early 1960's. With the advent of large-scale computing power, newer numerical methods have become available to predict equipment responses. This thesis is a comparative study of DDAM and ELSHOK (Elastic Shock); a new generation numerical shock response code. The limitations and strong points of both methods are examined using illustrative examples. Additional keywords: Finite element analysis; Finite difference theory; Elastic shock response; Explosive shock response; COmputer program documentation; User manuals; Mathematical models.
