Abstract:

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP ADVANCED CAPABILITIES FOR COMPUTER CODES IN PREDICTING THE DAMAGE INFLICTED ON NAVAL TARGETS BY UNDERWATER WARHEADS. THE PROPOSED RESEARCH EFFORT WILL TAKE SOME HIGHLY REGARDED, WELL DOCUMENTED, AND VALIDATED GENERAL PURPOSE CODES AND ADD CAPABILITIES TAILORED TO THE UNDERWATER WARHEAD DYNAMICS PROBLEM AND COMBINE ALL REQUIRED CAPABILITIES INTO ONE SOFTWARE FRAMEWORK. IT IS ANTICIPATED THAT THE FRAMEWORK WILL BE BASED ON THE DYNA, PISCES, AND XL CODES AND WILL INVOLVE THE ADDITION OF THE DAA AND AN INTERFACE BETWEEN THE 3-D FINITE ELEMENT DYNA AND THE 2-D FINITE DIFFERENCE CODE PISCES TO PROVIDE SOLUTIONS IN BOTH THE EXTREME AND MODERATE DAMAGE REGIONS. THE NEW CAPABILITIES WILL BE DOCUMENTED AND VALIDATED WITH TEST DATA. BY INCREASING THE NUMBER OF DIFFERENT PHYSICAL EFFECTS (LARGE DYNAMIC PLASTIC DEFORMATION, FLUID-STRUCTURE INTERACTION, SPALLING, ETC.) THAT CAN BE HANDLED BY THE PROPOSED SOFTWARE FRAMEWORK BY INCREASING ITS EFFICIENCY FOR RUNNING LARGER PROBLEMS, AND BY EASING THE BURDEN ON THE ANALYST WITH SOPHISTICATED MODEL GENERATORS AND OUTPUT PROCESSORS AND DISPLAY, MORE REALISTIC MODELS CAN BE ANALYZED. SEMI-AUTOMATED MODEL GENERATION, ADVANCED DATA PREAND POST-PROCESSING, AND EXPERT SYSTEM CAPABILITY WILL ALSO BE ADDED TO ASSIST IN THE MODELLING EFFORTS.
