Abstract

Fatigue crack growth (FCG) behaviour under variable (VA) amplitude loading is a subject that has been studied since 1970, with Elber’s contribution to fracture mechanics. Simple VA load sequences are most commonly used to study the load interaction effect phenomenon. Changes in the loading amplitude, so-called high-low sequence loading experiments, can introduce profound effects on fatigue crack growth. The purpose of this research is to test the applicability of a unified two-parameter FCG model—called UniGrow model—for the above mentioned loading conditions. Finally, the authors have made efforts to identify some uncertainty parameters to evaluate the prediction accuracy of the model.
