It is governed by many, often conflicting factors that typically include service requirements, design life, materials availability, database accessibility, manufacturing constraints, repair and replacement strategies, client preferences, and cost. The incorporation of computer-aided materials selection systems into computer-aided design and computer-aided manufacturing operations could assist designers by suggesting potential manufacturing processes for particular products to facilitate concurrent engineering, recommending various materials for a specific part based on a given set of characteristics, or proposing possible modifications of a design if suitable materials for a particular part do not exist. This report reviews the structural design process, determines the elements and capabilities required for a computer- aided materials selection system to assist design engineers, and recommends the research and development areas of materials database, knowledge base, and modeling required to develop a computer-aided materials selection system.
