In this study, the effects of compressive stresses on the crack tip parameters and its implication on fatigue crack growth have been studied. Elastic-plastic finite element analysis has been used to analyse the change of crack tip parameters with the increase of the applied compressive stress level.
As a common practice, the compressive (negative load ratio) excursions are ignored when analyses of fatigue crack growth in metals are conducted. However, recent experimental data on fatigue crack growth with intermittent compressive load excursions have shown that the use of this assumption leads i
