Abstract : The present investigation, the fatigue crack growth behaviour of surface cracked piping, pressurized base
straight component (PBSC 8-5) are performed on the basis of the linear elastic fracture mechanics (LEFM) principles. The
stress intensity factors available in the open literature are evaluated to predict the crack growth behaviour of the component
using the specimen tested material data. It is concluded that the available open literature stress intensity factor (SIF) solution
like ASM and Bergman for external surface cracked straight pipe case having the semi-elliptical crack profile predicts the
fatigue life of the component when having constant crack depth profile.
Index Terms— Fatigue; Paris equation; Stress intensity factor solution; Crack growth behavior; Power plant component.
