In bolted joints, various types of fractures (failures) may occur at various locations since the stress on the bolt-nut assembly is greatly affected by the geometry and the clamp force of the joint as well as the load acting on the joint. This study aim to develop the fault diagnosis database for bolted joints which can provide specialized and/or customized knowledges for individual design engineers. The structure of data module based on Hierarchical Fault Classification (HFC) method is proposed, and the user interfaces are discussed. The classified data offered by this database system are enable to search for technical information without any difficulty. To make the design procedure easier, the database has to include the detailed information of each fault mode including the typical picture and the location of the fracture, to assist the better understanding of complicated fault mechanisms. General versatility is also considered for the fault description which can be to applied to other machine elements in the future.
