The paper analyses simple models that simulate the effect of pipe bends on the stability of a circumferential through-wall crack in a Type 304 stainless steel piping system that is subject to fixed displacement loadings, which are appropriate for an accident condition. The instability criterion is e
## Abstnct-Proceeding from the experimentally vindicated basis that circumferential growth of a through-wall crack in a circular cylindrical 304 stainless steel pipe subject to bending loads, is associated with a constant crack tip opening angle, the stability of circumferential crack growth is an
This paper examines the fracture instability of a pipe, fabricated from a ductile material such as 304 stainless steel, in which a circumferential cross-section contains two symmetrically situated through-wall cracks, the pipe being subject to bending deformation. The theoretical analysis, which is
