In this paper some peculiarities of fatigue crack growth are considered, ones referred to curves of a crack length vs. a number of cycles or the rate of propagation vs. the range of stress intensity factor, i.e. curves typical of tests with overloads applied in cycles. Difficulties with the model-based description (based on the Wheeler retardation model) of fatigue crack growth have been shown. The modifications of the Wheeler retardation model have been presented, ones that improve capabilities of describing data which result from investigation into fatigue crack growth phenomena.
