| Abstract: | The transient temperature and stress fields in a quenched rectangular bar were computed and used to determine the stress intensity factors for midside and corner-edge cracks. The stress intensity factors, K 1, are presented as a function of time, flaw size, and aspect ratio. The variations of AT, along the crack edge are given and the self-limiting growth of the crack depth is discussed in relation to the nonlimited surface growth. |
