Abstract:
Great advances have been made in recent years in developing viable theories for stress corrosion cracking (SCC) and corrosion fatigue (CF), particularly with the advent of the Coupled Environment Fracture Model (CEFM) and the Coupled Environment Corrosion Fatigue Model (CECFM), respectfully. Both models are highly deterministic in that the model predictions are constrained by the natural laws, specially by the conservation of charge and mass, Faraday’s law of the equivalence of mass/charge, and by the traditional laws of chemistry. The outcome is that the models can predict the crack growth rate (CGR) under constant loading and under fatigue conditions as accurately as can be measured. The illustration of the application of the models to predicted SCC and CF damage in water-cooled nuclear power rector coolant systems is presented.
