Study on DFR method under corrosive environment for fatigue analysis

  • Received Date: 14 Jan 2003

  • Via transfer the influence of corrosive environment on fatigue life to that on detail fatigue rating equivalently, the DFR method under corrosive environment for fatigue analysis was established. The relation between the ratio of fatigue life under corrosive and normal environment and the corrosive convert coefficient of DFR was obtained by the standard S-N curve equation, thus the determination method of the convert coefficient was presented, in which the parameter c was shown to have little influence on its precision. Based on the assumption that the influence of pre-corrosion on ground and the influence of corrosion in flight are independent, a method for separation pre-corrosion and corrosion fatigue was proposed.
