An Evaluation of Fatigue Crack Growth in a Reactor Steel in Air and Aqueous Environments Considering Closure Effects

Original language description

The experimental programme described in the paper was aimed at an evaluation of fatigue crack growth (FCG) rate and threshold conditions in a reactor pressure vessel steel in laboratory air and in simple aqueous environment. Though the main target of thework was to enlarge the data basis for possible future needs of defect and risk assessment, an emphasis was put on an evaluation of crack growth mechanisms. It was shown that despite some recent works infirming crack closure phenomenon itself or methodsof its evaluation, crack closure explained near-threshold fatigue crack behaviour in the specific case of the reactor steel in air conditions and it was in a direct consistency with results of fractographical analyses. It was shown that strong closure effect was responsible for such the behaviour.
