This paper is concerned with the problem of inclined slip planes as a model of the plastic yielding region at a crack tip under conditions of plane strain. Some of the disagreements in the literature are discussed and comparisons are made with the results in the present study. To characterize the location of the plastic zones, an ad hoc criterion is used to choose an angle of inclination for the slip bands.
