Abstract:

Structural integrity is not only the primary factor determining the safety and lifespan of aeronautical structures, but poses significant challenge to the application of novel materials, structures, and techniques in the field of aviation. Clarifying and enhancing the structural integrity performance of advanced materials and structures can facilitate the utilization of the outstanding capabilities in aviation structures, thereby achieving more reliable, efficient, and economical aviation structural goals. The present paper systematically reviews the main achievements and recent work conducted by member countries of the International Committee on Aeronautical Fatigue and Structural Integrity (ICAF) in the past years of this field. Moreover, this paper introduces the recent advancements made by scholars from various fields in terms of the fatigue life of advanced materials, structures, and techniques, to stimulate continuous attention of researchers in aeronautical structural field towards the progress and issues on the aviation structural integrity. On this basis, combining with the extensive progress made in material, structural, and techniques domains in recent years, along with emerging demands for aeronautical structural performance, this paper also presents suggestions and prospects for the fatigue research of novel materials, structures, and techniques, as well as the design of future aeronautical structures, in order to further promote the development of this field.

Key words: aeronautical structures, advanced materials, advanced techniques, structure integrity, fatigue life
