FEASIBILITY STUDY OF SCALED SURFACE SHIP MODEL FOR UNDEX EXPERIMENT

SHOCK VULNERABILITY IS AN IMPORTANT DESIGN CONSIDERATION FOR NAVAL SURFACE SHIPS AND SUBMARINES. ALTHOUGH ANALYTICAL PROCEDURES EXIST FOR EVALUATING THE RESPONSE TO SHOCK OF ELASTIC STRUCTURES IMMERSED INWATER, VERIFICATION IS BY MEANS OF SHOCK TESTS. THE CURRENT PRACTICE OF SHOCK TESTING FULL SCALE SURFACE SHIPS IS COSTLY AND DOES NOT FACILITATE THE DEVELOPMENT OF NEW HULL FORMS AND STRUCTURES. THE PRIMARY OBJECTIVE OF THE PROPOSED STUDY IS TO EVALUATE THE FEASIBILITY OF SCALED MODEL SHOCK TESTING FOR SURFACE SHIP DESIGNS. THIS WORK WILL ENTAIL DEFINING PHENOMENA IMPORTANT TO UNDERWATER EXPLOSIVE SHOCK, DETERMINING RELEVANT SCALING RELATIONSHIPS, AND EVALUATING CONFLICTING REQUIREMENTS FOR SCALING. TO THE EXTENT POSSIBLE, THE EXISTING DATA BASE OF SURFACE SHIP SHOCK TESTS WILL BE USED TO VERIFY OR SUPPLEMENTANALYTICAL RESULTS. BASED ON THE CONCLUSIONS OF THIS STUDY, GUIDELINES FOR PHYSICAL TEST HARDWARE WILL BE DEVELOPED.
