Abstract

Abstract This paper is concerned with K r– L r failure assessment diagrams when they are applied to a flaw in the vicinity of a stress concentration. Earlier work by the author has highlighted the strong effect of geometrical parameters on the K r– L r failure assessment curve for such a situation. The earlier work had a particular focus on the small L r regime, which was studied via use of the equivalent elastic crack procedure. The present paper proceeds to the other extreme and focuses on the large L r regime for which, as with the small L r regime, there is a strong effect of geometrical parameters on the failure assessment curve.
