Mode-I crack growth in an elastic perfectly-plastic material under conditions of genera&d plane stress has been lnvestigatcd. In the plastic loading zone, near the plane of the crack, the stresses and strains have been expanded in powers of the distance, y, to the crack line. Substitution of the exp

The analysis of this paper is suitable not only for small scale yielding but also for large scale yielding. In this paper, the usual suggestion of small scale yielding has not been adopted. The accurate elastic stress and displacement fields (i.e. Westergaard's fields) for a mode III crack in an inf
