✦ Synopsis

Abs&aet-Based on micrct and macro fracture mechanics, the basic equations for the general configuration ofacracL(OTaIlOtCh)~aSlip~4tt0bbhred.Asaspcchl~,theeoclscieatsofmPturl~in stress intensity factors are calculated for the critical configuration of them corresponding to the low stress brittle fracture.

The codf&nta of mutual interaction are given in terms of a simple and analytical formula with a sufliciently good approximation. Furthermore, both the stress intensity factqrs at the tip of the crack and at the end of the slip band are obtained in simple forms applicable to fracture problems.
