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

โฆ Synopsis
The dynamical processes of the nucleation and propagation of stress corrosion cracking (SCC) of low-alloy steels with a wide range of tensile strength in gas and aqueous solution of HZ.7 were followed metallographically by using a polished WOL type constant deflection specimen. The results show that if

In this paper, based on the three-dimensional flow theory of plasticity, the fundamental equations for the plane strain problem of elastic-perfectly plastic solids are presented. By using these equations the elastic-plastic fields near the crack tip growing step-by-step in an elastic incompressible-
