Web-based material data knowledge base and expert system

Very important task which needs to be addressed ever earlier during product development process is choice of proper material. In order to do this, suitability of different materials must be evaluated, for which, their properties and parameters describing their behaviour, must be known. In case that experimental characterization of the material can not be performed, choice of the material can be improved by: a) increasing availability, searchability and comparability of knowledge on material behaviour ; b) increasing applicability of methods for estimation of material properties as well as by supporting their improvement and further development ; c) educating users by improving the level of their knowledge of material properties and methods for their estimation. In proposed paper, development and implementation of web-based system i.e. information service which addresses above mentioned issues are discussed. Mentioned web-based service consists of: dedicated website, interactive, searchable and user-expandable database containing data properties of design-relevant metallic materials, and knowledge base and knowledge-based expert system (web application) for selection and use of methods for estimation of advanced material parameters (cyclic, fatigue) from their monotonic properties such as hardness and ultimate strength Rm
