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. 606 $aStructural design$xData processing 606 $aMaterials$xData processing 615 0$aStructural design$xData processing. 615 0$aMaterials$xData processing. 676 $a624.1/7 712 02$aNational Research Council (U.S.).$bCommittee on Application of Expert Systems to Materials Selection During Structural Design. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910957181403321 996 $aComputer-aided materials selection during structural design$94351585 997 $aUNINA
