The brittle fracture resistance of a pipe with the circumferential edge crack on thermal shock is determined by a maximum J-integral value at the stage of plastic strain development near the crack tip. In an elastoplastic metal, the value of J-integral on thermal shock reaches its maximum with an increase in strain energy near the crack tip.
