A theory of stable crack growth, for generalized plane stress conditions, is presented which is based upon a Dugdale model of plasticity and an energy balance approach to fracture. Several forms for the rate of energy dissipation in the plastic zone are considered. It is shown that the J-integral, w
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
