An expert system, which diagnoses the causes of failure of environmentally assisted cracking (EAC), based upon fractography has been developed. The system uses the OPS83 programming language expressing rules in a manner of production rules and is composed of three independent subsystems, which respectively deal with EACs of high-strength or high-tensile strength steel, aluminum alloy, and stainless steel in dry and humidified air, water, and aqueous solutions containing Cl, Br or I ions. The concerned EAC issues cover stress corrosion cracking (SCC), hydrogen embrittlement, cyclic SCC, dynamic SCC and corrosion fatigue as well as fatigue and overloaded fracture. The knowledge base covers the rules relating to not only environments, materials, and loading conditions, but also macroscopic and microscopic fracture surface morphology. In order to deal with vague expressions of fracture surface morphology, Fuzzy theory is used in the system, and the description of rules about vague fracture surface appearance is thereby possible. Applying the developed expert system to case histories, accurate diagnoses were made. We discussed the related diagnosis results and usefulness of the developed system
