INVESTIGATION OF BULGING EFFECTS ON PROPAGATION OF 1-BAY AND 2-BAY LONGITUDINAL CRACKS WITH BROKEN/INTACT STIFFENER
A.S. Kim, TsAGI, Russia
Comparison of bulging models shows that using models of Swift and of Chen&Schijve gives the best agreement with experimental data. For these models new technique of calculation of duration of 2-bay longitudinal crack with broken stiffener was suggested. Comparison of calculation results and experiment demonstrated excellent agreement of calculation results with experimental data.
