Corrosion fatigue has been identified as one of the leading causes of failure among the various damage mechanisms that affect the structural integrity of aircraft structures. Operation of aging aircraft under a corrosive environment may cause failure of the various parts due to initiation and propagation of corrosion fatigue cracks. Scheduled maintenance and inspection of aircraft components in advance may prevent such failures. Establishment of models for predicting corrosion fatigue will be helpful in designing a maintenance program based on the residual life to avoid failure. A particle swarm optimization method was used to investigate the corrosion fatigue problem. The optimization procedure is used in redesigning the operating environment to achieve desired corrosion fatigue properties for an aircraft panel/material. The operating parameters that would cause a structure to have maximum fatigue properties were obtained from the optimization simulation. The results of operating parameters obtained through the optimization procedure are reasonable and demonstrate the feasibility of the approach for estimating the corrosion fatigue of aging structures.
