Incorporating materials expert systems into CAD/CAM 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 book reviews the structural design process, determines the elements, and capabilities required for a materials selection expert system to assist design engineers, and recommends the areas of expert system and materials modeling research and development required to devise a materials-specific design system.Structural designData processingMaterialsData processingStructural designData processing.MaterialsData processing.624.1/7National Research Council (U.S.).Committee on Application of Expert Systems to Materials Selection During Structural Design.MiAaPQMiAaPQMiAaPQBOOK9910957181403321Computer-aided materials selection during structural design4351585UNINA
