文档介绍：A knowledge-based system for materials selection in mechanical engineering design Abstract This paper studies various work on the development puterized material selection system. The importance of Knowledge-based system ( KBS ) in the context of concurrent engineering is explained. The study of KBS in material selection in an engineering design process is described. The development in materials databases, which sometimes serve as material selection packages, is also discussed. The use of KBS in material selection and the application in the domain of polymeric-posite are chosen as typical examples. 2001 Published by Elsevier Science Ltd. 1. Introduction Materials selection isa task normally carried out by design and materials engineers. Gutteridge and Water- man [1] described the aim of materials selection as the identification of materials, which after appropriate manufacturing operations, will have the dimensions, shape and properties necessary for the product ponent to demonstrate its required function at the lowest cost. For the purpose of material selection, thousands of data would be needed to characterize all the grades of materials. Many selection systems are available to help design engineers to choose the most suitable materials. At the most basic level, design engineers could use tables of material properties in data books. However, data sheets are plete and once publ
