Determination of Stress Intensity Factors in the Welded Joint Between the Header and Shell of Pgv-1000m Steam Generator with a Defect in the Form of a Cavity with a Crack

  • Published:
Strength of Materials Aims and scope

The stress intensity factors in the welded joint between the header and shell of steam generator with a defect in the form of a cavity with a crack has been investigated. The influence on the history of thermomechanical loading on the stress intensity factor at the crack tip has been analyzed. A comparative analysis of the stress intensity factors for the crack and cavity with a crack has been performed.
