STATE-OF-ART AND FUTURE OF AIRCRAFT STRUCTURE DESIGN AND STRENGTH ANALYSIS

This paper reviews the state-of-art and the future of the design and the strength analysis of aircraft structures in brief. The emphasis is put on discussing some important topics for designers and researchers in this field so as to prompt engineering design and scientific research and to enhance the development of aeronautical science and technology.After a general review, the discussion covers the following subjects: The modern procedure of aircraft structure design, the finite element method and the structure analysis program system, the mode active control technology and analysis method, the application of fatigue and fracture, the advanced composite structures, the serious environment conditions, the reliabitistic analysis for structures and structural test etc. .While the content mainly deals with the aircraft structures, quite a lot of its parts are concerned in or adapted to the aerospacecraft structures as well.
