| Popis: | Results of analytical studies of a cooperative joint fracture mechanics programme are presented. The programme is concerned with bending of original DN 700 straight pipes with circumferential through-wall cracks. Material is the austenitic stainless steel 316L SPH. This paper is following a previous publication on the experimental part (Nucl. Engrg. Des. 108 (1988) 447–456). Details are given on studies using the finite element technique, the “Screening Criterion” of Battelle, the double criteria approach (F.A.D.), the GE/EPRI handbook and the engineering treatment model (ETM). Most data are given for crack initiation; however, instability and corresponding crack extension are also considered. |
