Web-Based Expert System in Fatigue and Fracture Analysis

An expert system in fatigue and fracture analysis based on Web is developed in this paper. The system consists of six functional parts: a general inference engine, some knowledge bases, a context, an interpretation engine, a bases administration system and the interface (includes browser, Web-server, etc.). It can simulate a human expert to make analysis and design scheme for some typical structural components: pressure vessels, huge rotation constructions, welded structures, etc. It is an open system which may be broadened and perfected to cover a wider range of application through the modification and enlargement of the knowledge and data bases on Web.
