Surface cracked plates are typical structure elements with postulated cracks. Accurate calculation of stress intensity factors for cracked plates subjected to arbitral stress distribution is essential to predict the crack growth behavior due to fatigue or SCC. Some stress intensity factor solutions for cracked plates have been proposed so far. In this paper, these solutions were compared each other from the viewpoint of the applicability to actual plant components, and a solution was selected which could be suitable for codification.
