Light-weight materials selection for High-Speed Naval Craft

CIVINS / A decision analysis study was conducted on the process of materials selection for high-speed naval craft using the Modified Digital Logic (MDL) method. The purpose is to show how this method along with Ashby's material selection process can be integrated to provide a comprehensive tool designed specifically for light-weight material optimization. Using Ashby's Material Selection Charts and the MDL method, a step by step material selection process is outlined. Furthermore, a comparison of the materials based on equivalent plate uni-axial ideal elastic compressive stress was completed using the American Bureau of Shipbuilding (ABS) Guide for Building and Classing High-Speed Naval Craft and then an evaluation was done to optimize material selection depending on the designer's preference for weight and cost, The potential materials for evaluation were selected using Naval Sea Systems Command (NAVSEA) references for the most current materials in use, or being evaluated, for light weight naval construction. The results demonstrate the feasibility of using the MDL method to select one or more materials based on desired mechanical and structural characteristics. The study also introduces the potential use of non-traditional materials in Naval Architecture, such as Ultra High-Performance Concrete Composite (UHP2C) DUCTAL. / Contract number: N62271-97-G-0026. / CIVINS
