A general method to predict the crack propagation of anodic dissolution corrosion fatigue is developed
in this paper. Crack propagation of corrosion fatigue is presented as the result of the synergistic interactions of
mechanical and environmental factors, and corrosive environment accelerates crack propagation mainly in term
of anodic dissolution. By studying the variation of mechanical energy and electrochemical energy of anodic
dissolution during the crack propagation process, an explicit expression of crack propagation rate is derived by
the conservation of energy. The comparisons with experimental data demonstrate the validity of the proposed
model. Moreover, the applicable upper-limit crack length for steady crack propagation is determined and the
crack propagation life is evaluated.
