Desktop Software for First Order Approximations of the Effects of Blast and Ballistic Impact on Vehicles Navy SBIR FY2011.3 Sol No.: Navy SBIR FY2011.3 Topic No.: N113-173 Topic Title: Desktop Software for First Order Approximations of the Effects of Blast and Ballistic Impact on Vehicles Proposal No.: N113-173-0282 Firm: SURVICE Engineering Company 4695 Millennium Drive Belcamp, Maryland 21017-1505 Contact: James Walbert Phone: (703) 221-7370 Web Site: www.survice.com Abstract: A fast, simple, desktop software tool that can predict, with a high degree of certainty, the effects of blast and ballistic events on ground combat vehicles is proposed. This effort builds upon past performance on and present work with advanced survivability algorithms to create a simple software interface that allows rapid user modeling and simulation to execute the necessary multiple iterations. Phase I efforts will focus on creating an integrated desktop software tool that will enable efficient calculation of (1) V50/VXX, and penetration effects of various projectiles in armor; (2) Crater dimensions from charge weight; (3) Pressure and impulse time histories for surface bursts; (4) Two dimensional blast forces with reflected pressure, impulse histories, and three dimensional plots and animations of the blast; (5) Exterior ballistics data; and (6) Plate deflection for homogenous materials, likelihood of plate fracture, and response of a virtual accelerometer anywhere within a modeled structure. Subsequent Phase II program efforts would optimize software performance, and verify and validate the desktop software using existing unclassified ballistic test data to specified performance levels. Benefits: The Phase I program will develop a simple yet rigorous desktop-based software tool to evaluate vehicles subjected to explosions and ballistic impact. Successful completion of accurate and rapid desktop-based software for first order approximations of the effects of blast and ballistic impact on vehicles will allow commercial developers and original equipment manufacturers to model survivability outcomes in a fraction of the time of traditional hydrocode programs. The proposed software package will enable commercial industry to conduct analysis with multiple material configurations and with multiple iterations without specific software, operating systems, or specialized training.
