In this study, three-dimensional finite element residual stress analysis of a small bore penetration nozzle was performed using the commercial finite element program, ABAQUS. Comparing with the real PWSCC (primary water stress corrosion crack) history, it is identified that the finite element analysis is valid in the viewpoint of PWSCC initiation and growth. Parametric finite element residual stress analysis was systematically implemented in order to investigate effect of the geometric variables including nozzle outer diameter/thickness, buttering thickness, angle between central axes of head & nozzle, etc. on the residual stresses. As a result of the parametric analysis, it is found that effects of the nozzle outer diameter and the angle between central axes of head & nozzle on the maximum residual stress generation location and magnitude are significant while effects of the head thickness, the buttering thickness, the weld depth, and the nozzle thickness to outer diameter are insignificant.

Stress analysis of the butt circular shaft with three uniformly distributed metal columns subjected to external torques are carried out by using three-dimensional finite element method. The loading capability of the butt circular shaft is measured. It was found that torque acting on the cross-section of adhesive layer is simultaneously withstood by the adhesive layer and the metal columns; The ratio of the torque withstood by metal columns to that withstood by adhesive layer increases with increase of the ratio of Young’s modulus of metal columns to that of the circular shaft; The metal columns enhance and improve the reliability of the joints; The strength of the butt adhesive circular shafts increases with increase of the ratio of the yield stress of the metal columns to that of circular shafts.
