Verification and Optimization of Advanced Finite Element Modeling Techniques for Complex Submarine Hull Structures

In modern submarine design, the effort to produce more efficient, lighter and less expensive structures drives the analysis beyond simple historic empirical techniques towards a higher reliance on finite element modeling (FEM) analysis. The problem increases in complexity with the choice of FEM modeling techniques varying widely between different organizations in their choice of criteria such as element formulation, mesh density, assumptions, and boundary conditions. To solve this problem MTech will develop a Finite Element Manual to be used by NAVSEA and the Shipyards as a design tool to ensure FEM techniques are consistent and appropriate for the design detail. MTech will combine conventional techniques with innovative solutions to reduce US Navy cost and schedule. The MTech design tool will ensure equivalent tools are used, document common knowledge of best practices, provide accurate guidance and provide test verified techniques all while providing the analyst maximum flexibility.
