On Probabilistic Fatigue Crack Growth Behavior under Constant Amplitude Loads
In this paper, an analysis of fatigue crack growth (FCG) behavior from a statistical point of view has been carried out. Fatigue crack growth tests were conducted on sixteen pre-cracked compact tension (CT) specimens of the pressure vessel (SPV50) steel in controlled identical load and environmental conditions. The assessment of the statistical distribution of fatigue crack growth experimental data obtained from SPV50 steel was studied and also the correlation of the parameter C and m in the Paris-Erdogan law was discussed. The probability distribution function of FCG life and FCG rate seems to follow the 3-parameter Weibull.
