Fire Simulation and Residual Strength Prediction Tool for Aluminum Ship Structures During and After Fire: System Integration Navy SBIR FY2010.2 Sol No.: Navy SBIR FY2010.2 Topic No.: N102-173 Topic Title: Fire Simulation and Residual Strength Prediction Tool for Aluminum Ship Structures During and After Fire: System Integration Proposal No.: N102-173-0655 Firm: Weidlinger Associates, Inc. 375 Hudson St FL 12 New York, New York 10014-3656 Contact: Najib Abboud Phone: (212) 367-3074 Web Site: http://www.wai.com Abstract: In this proposal, we will develop and implement general thermal coupling schemes so that thermomechanical structural solvers, specialized fire-dynamics CFD codes and other thermal simulators may be employed in the solution of practical fire mechanics problems of interest to the Navy. This development will enable large-scale and physically accurate simulations of fire, structural degradation due to thermal effects, and fire evolution due to structural failure. The proposed Weidlinger Aluminum Structure Simulation Platform (WASSP) is conceived as an Application Programming Interface (API) which mediates the synchronized transfer of different classes of data between codes. The research that underlies this development is mainly concentrated to developing the appropriate coupling schemes that both respect the numerical performance and stability of the algorithms exchanging data and the realistic physics of the problem, including the orders of magnitude time-scale differences in the evolution of states in different domains. Benefits: The physcis-based computational platform technology for fire effects on aluminum ships will deliver numerous direct and indirect commercial benefits. The immediate commercial application will be to the design and analysis of aluminum Navy ship structures under fire conditions. This proposed SBIR development has the potential to impact many of our existing markets: naval technology, medical imaging, sonar, and acoustic device engineering. The technology is also well positioned for the inevitable adoption of performance-based approaches to fire protection for structures in many industries, including the construction industry. Return
