Abstract

An alternative way of interpreting the Kitagawa-Takahashi diagram for structural components is proposed. With this aim, the equivalent initial flaw size (EIFS) model, as a way of defining the initial defects of the structural components is used in conjunction with the probabilistic S-N model proposed by Castillo and Canteli, thus allowing the probabilistic distribution of the EIFS to be generated and, consequently, a probabilistic definition of the KT diagram (P-KT) to be achieved. The proposed approach is applied to a notched plate made of P355NL1 steel, the results of predictions are analyzed and the deviations discussed.
