Abstract EN
In this paper a theoretical model was developed to predict the fatigue crack growth behavior under the constant amplitude loading with single overload.
In the proposed model, crack growth retardation was accounted for by using crack closure and plastic zone.
The virtual crack annealing model modified by Bauschinger effect was used to calculate the crack closure level in the outside of retardation effect region.
And the Dugdale plastic zone model was employed to estimate the size of retardation effect region.
A sophisticated equation was developed to calculate the crack closure variation during the retardation area.
Model validation was performed in D16 aluminum alloy and 350WT steel specimens subjected to constant amplitude load with single or multiple overloads.
The predictions of the proposed model were contrasted with experimental data, and fairly good agreements were observed.
