Abstract: The boundary element method is employed to determine polynomial influence coefficients of stress intensity factors, KI , for a semi-elliptical crack in internally pressurized thick-walled curved ...

Abstract: Fatigue and leak-before-break calculations for a pressure vessel require knowledge of the stress intensity factor at the deepest point of a straight- or curved-fronted (semi-elliptical) surface ...

Abstract: This paper presents T-stress solutions for an internal edge crack in thick-walled cylinders. Elastic fracture mechanics analysis using the boundary element method (BEM) is performed to determine ...

Abstract: Pressure vessel steels exhibit the Bauschinger effect that significantly reduces post-autofrettage residual compressive hoop stresses in the near-bore region in comparison with ‘ideal’ (elastic-perfectly ...
