Evaluation of overload effects on fatigue crack growth and closure
Borrego, L. P.; Ferreira, J. M.; Pinho da Cruz, J. M.; Costa, J. M.Fatigue crack propagation tests with single tensile peak overloads have been performed in 6082-T6 aluminium alloy at several baseline [Delta]K levels and stress ratios of 0.05 and 0.25. The tests were carried out at constant [Delta]K conditions. Crack closure was monitored in all tests by the compliance technique using a pin microgauge. The observed transient post-overload behaviour is discussed in terms of ove...
