The Fatigue in Aircraft Corrosion Testing (FACT) Programme

摘要: Abstract : Failure by fatigue and degradation corrosion continue to be major considerations aircraft design. Environmental effects influence both initiation propagation of cracks, dynamic loading may cause more rapid deterioration protection systems. Therefore the conjoint action environmental attack, i.e., fatigue, requires special attention. Many tests have been done on aluminum alloys. However, few included critical structural details like joints, under realistic cyclic load histories in service-like environments. Even fewer used practical These aspects are specifically addressed FACT programme its predecessor CFCTP programme. The results provide a significant contribution understanding should encourage further investigation this difficult challenging area aerospace technology.
