โœฆ Synopsis

This paper deals with the determination of stress intensity factors for plane cracks which are at or near interfaces. The interface may be straight or curved and be a free surface or between two elastically dissimilar materials. Any bulk stress field may be catered for as may partially closed cracks. The solution technique used is to distribute line singularities or 'dislocations'; details of the formulation of the relevant integral equations and their solution are discussed.

A micro crack can be initiated by coalescing dislocations piled up along a slip plane. This mechanism was firstly proposed by Zener and later on analyzed by Stroh. The micro crack is thus called Zener-Stroh crack, which is a counterpart of the well-known Griffith crack in linear elastic fracture mec
