Phase II Full Proposal for SBIR contract for topic: N171-059 – “Verification and Optimization of Advanced Finite Element Modeling Techniques for Complex Submarine Hull Structures”. This NAVSEA Phase II SBIR proposal describes the technical objectives and work plan toward the creation of a manual of finite element modeling(FEM) procedures for complex submarine hull structures, with accuracy validated through analysis and testing. The proposed approach builds on the feasibility efforts of Phase I using FEM analysis, test validation, sensitivity studies, index problems and industry “best practices”. The analysis tasks identify FEM modeling criteria limitations specific to complex submarine geometry and provide guidance to insure correct interpretation of analysis results. Test validation plans are identified, including reduced-scale risk mitigation testing within Phase II. The proposed objective and work plan show a path toward development of a FEM manual for complex submarine hull structures, which will avoid cost and schedule overruns caused by analysis method conflicts between the DON technical community and submarine design yards. The resulting manual can be extended for commercial use to the shipbuilding, oil exploration and other industries.
