Abstract

The situation encountered by a crack in a dissimilar metal joint is analysed using a weight function method applied to a Dugdale crack model. The stress intensity factor at an effective crack tip located in the vicinity of the interface can be calculated from the weight function for a constant pressure load system, based on the principle of elastic stress superposition. The effects on the stress intensity factor and the crack tip opening displacement of a hard transitional zone, which is developed near the interface, are discussed.
