Fire Simulation and Residual Strength Prediction Tool for Aluminum Ship Structures During and After Fire: Constitutive Models and Residual Strength Module 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: Constitutive Models and Residual Strength Module Proposal No.: N102-173-0665 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: The proposed work concentrates on the development of a Constitutive Models and Residual Strength finite element simulation module that would be one module in an overall coupled framework, with other modules resolving the fire dynamics (growth and spread), the heat transfer across materials, pyrolysis, etc. A successful Phase I of the project will assess and demonstrate the feasibility of the proposed approaches for simulation of aluminum panels, decks and/or components subjected to fire as well as mechanical loads at various strain rates. Two alternative tracks: creep description and classical viscoplasticity framework will be tested for accuracy and efficiency. In conjunction with the Navy, both approaches will be validated against GFI experimental test data. Development of a complete structural assessment module for fire effects and residual strength simulation for aluminum ships during and after fire is contemplated for Phase II. 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, aeronautics, offshore oil industry. Return
