G. I. Nesterenko
TsAGI, Russian Federation

Keywords: fail safe, design goal, damage tolerance, fatigue

Test-analytical results of investigating into the fatigue, fail-safety and damage tolerance of Russian aircraft are presented. Stresses in wide-body aircraft structures are given. Fatigue life curves for wing and fuselage structures are generated. Residual strength data are presented for these structures having a skin crack under the broken stiffener. Generalized curves for skin crack duration under the broken stiffener are presented
