Surface Ship Shock trials play an essential rule in ship test and evaluation (T&E), and Live Fire Test and Evaluation (LFT&E) requirements for the lead ship of each new construction shock hardened ship class. These tests provide insight into platform vulnerabilities with respect to close proximity underwater explosion (UNDEX) events. The high cost of conducting ship shock trials has lead to a significant effort to develop modeling and simulation capabilities that can provide decision-making data comparable to that gained from the actual tests. Unfortunately, efforts to capture the response of a ship's structure to an UNDEX event require extremely large and complex finite element models of not only the ship's structure but the surrounding fluid. This fluid volume is required to capture the effects of the cavitation caused by the UNDEX shock waves. The computational expense of running these finite element models is tremendous. This thesis reviews the work on this subject completed at the Naval Postgraduate school. Additionally, it provides further investigation into the amount of the fluid that must be modeled to accurately capture the structural response of a 3D finite element model and presents a second generation finite element model of the USS JOHN PAUL JONES (DDG 53) for use in 3D analysis.
