Method for Fatigue Test of Aircraft StructuresConsidering Corrosion Influence

  • Received Date: 06 Jul 2001

  • Considering the influence of corrosive environment, a valuable method for fatigue test of aircraft structures at room temperature and in the air is presented. The service process of an aircraft is simplified into pre-corrosion under the ground environment and corrosion fatigue during flight, and corrosion influence coefficient curves of aircraft structures are obtained. According to the damage equivalent principle, the fatigue life indexes of aircraft structures at room temperature and in the air are deduced based on the designed fatigue life index and average flight time per year under corrosive environment, so the testing object life can be determined.
