Trade-Off Study for Materials and Fabrication Processes for Advanced High Performance Ship Applications. Volume I.

摘要

The objectives of the study were to:Identify the mission and system criteria for major structural systems for advanced ships;establish guidelines for the selection of materials and processes for high performance ships;conduct trade studies of candidate materials and fabrication processes to evaluate their cost effectiveness and practicality;and,make recommendations for future effort required to fill data voids identified by this study and a plan to accomplish that work. The output of the study includes (1) a list of mission and system criteria that need to be identified prior to the material/fabrication concept selection, (2) a set of guidelines for the selection of material/fabrication concepts applicable to specific mission,system and design criteria, (3) a collection of applicable material and process data, (4) procedures for establishing a fabricability index and a cost index for materials, (5) three trade studies on representative structures,and (6) recommendations for future work.
