    Abstract

    Studies were carried out on the crack initiation and propagation laws under high-temperature creep, fatigue, and creep-fatigue multiplication conditions for notched specimens of SUS 304 stainless steel. For crack initiation life, it was found that relative notch opening displacement (RNOD) can be used. Furthermore, the remaining part of crack initiation life can be predicted by RNOD criterion: that is, by recording RNOD with respect to the suitable time within the service term and extrapolating the data with a straight line until the line intersects the critical value of RNOD. The crack propagation life was expressed by a thermally activated type equation in explicit terms of independent parameters such as applied stress and temperature.
