SERVICE LIFE PREDICTION OF COMPOSITE STRUCTURES OF AIRCRAFTS

摘要：

The most important problem for composite structures of aircrafts is to ensure reliability for long-time operation. Actually all aircrafts are operated under various fatigue loads and various aging environmental conditions. In order to consider the combined effects of fatigue loads and aging environment, new concepts of Life Vector, Life Envelope Curve and Life Envelope Surface of Composite Structures of Aircrafts are introduced to illustrate the life characteristics of composite structures of aircrafts. The sketch and establishment methods under different operational conditions are presented later. Then the linear damage accumulation rule is recommended to predict the residual fatigue life and calendric life of composite structures of aircrafts in different operational conditions.
