Abstract
In this paper, statistical aspects of the constant stress-rate test were investigated. The effects of the number of specimens on the subcritical crack growth parameters were examined. The grooved disk specimens were used to determine the fracture strength. 7 groups of fictitious data sets with the number of specimens of 5, 7, 10, 20, 40, 80, and 160 at each stress rate were generated by Monte Carlo simulation using the Weibull parameters obtained from the grooved disk tests. Also, the distribution form of the subcritical crack growth parameters and the relation between the parameter A and n was determined.
