Ensuring structural damage tolerance of russian aircraft

This paper considers most common problems related with structural integrity of civil aircraft in Russia taking into account the development of regulatory requirements, prevention of multiple site fatigue damages, improvements of crack resistance of structural materials, optimizations of aircraft type structures, development of methods for residual strength analyses of stiffened structures as well as for crack growth rates under random service loading spectra, experimental results for crack resistance degradation, methods to prevent structural failure for long operated aircraft due to corrosion.
