✦ Synopsis

The quasi-static growth of a crack in an elastic-creeping material under antiplane shear or mode III loading is investigated. The creep response of the material is assumed to be governed by a power-law between the creep strain rate, creep strain, and stress. While this law is capable of describing elastic-primary, secondary, or tertiary creep, the major emphasis of this paper is on crack growth in the elastic-primary creep regime. The asymptotic crack-tip stress and strain fields for a quasi-statically extending crack in an elastic-primary creeping material are developed. This is followed by a finite element analysis to determine the complete stress and strain fields within the confines of small scale yielding. These fields are then compared with the asymptotic ones to establish the size of the zone of dominance of the crack-tip fields.
