Keywords : plastic pipes * residual stresses * stress intensity factor
Subject RIV: JL - Materials Fatigue, Friction Mechanics
The expression for the stress intensity factor KI corresponding to a plane axial crack in the pipe wall exposed to combination of service and circumferential residual stress is presented. It is supposed that the expression holds for a wide group of plastic pipes made of similar materials and produced by the same technology.
