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.
Ah&act-It has been suggested that the crack closure concept can account for the retardation in crack growth rate following removal of tensile overloads. To test this possibility measurements of effective stress were made on center notched cracked specimens during tests in which tensile overloads wer
