Fractographic reconstitution of fatigue crack growth in integrally stiffened panels

Original language description

A research program was focused on design and experimental verification of fracture marking of integrally stiffened panels during the fatigue tests under flight-by-flight spectrum loading and testing the effectiveness of various fractographic methods. Thepanels represent complex testing models of aircraft wing parts. Three kinds of cyclic loading were used: constant amplitude loading (CAL), flight-by-flight type spectrum loading without marking and flight-by-flight spectrum with marking. Different methods were applied for fractographic reconstitution of fatigue crack growth: a) measurement of striation spacing, b) identification of beach marks, c) image textural analysis of SEM images of fatigue fracture surfaces (textural fractography) aimed at morphological features oriented in the direction of crack growth. The obtained crack growth curves enable the study of the influence of loading spectrum on crack growth kinetics and comparison of the different fractographic methods.
