The development of an expert system on fatigue fracture of the roll

In this paper,based on the analysis of roll fatigue fracture,an expert system for the engineering application of fatigue and fracture theory was developed.The essential function is to apply the theory of fatigue and fracture to the analysis of the roll and obtaining the comprehensive appraised result in the end.The main task of the ES is to assess rolls by using K criterion.It can be applied to preventing the roll from suddenly breaking and serious trouble of occurrence.
