A description is given of a method for calculating the fatigue strength of airframe structures with an existing crack. The method makes it possible to determine the dependence of crack length on the duration of usage (number of kilometers covered in flight or the number of flight hours). The technique was used to study fatigue strength in samples with and without strain hardening, showing the influence of strain hardening on crack propagation parameters during variable amplitude loading (based on load spectra for transport aircraft). The test data show the possibility of a significant reduction on the rate of crack propagation with the aid of properly chosen strain hardening. (Author)
