Abstract
The selection of the proper materials for a structural component is a
critical engineering activity. 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.
