Stress intensity factors for long longitudinal and complete circumferential cracks under stress gradients were calculated using a weight function method. The weight functions were obtained by a method proposed by Petroski and Achenbach [3] and by a finite element fit procedure. Excellent agreement was obtained with finite element results of Labbens, et al. [7].
