Abstract
Corrosion can accelerate the crack growth and weaken the initial fatigue quality (IFQ). To evaluate the economic life for aircraft structure in corrosive environment, the crack exceed probability is analyzed by using the probabilistic fracture mechanics approach (PFMA) and crack initiation approach (CIA) in corrosive environment, and the failure probabilities for the critical component, single aircraft and fleets are obtained by assuming the crack exceed number follows the binomial distribution. The failure probability control approach (FPCA) for duration analysis in corrosive environment is founded and used to evaluate the economic life for F × fighter.
