Degraded Piping Program. Phase II. Semiannual report, October 1984-March 1985. Vol. 2
This second semiannual report summarizes efforts within the first year of the Degraded Piping Program. The objective of this project is to verify and improve fracture mechanics analyses for nuclear piping. This report contains the statements of the specific objectives of each task of the program, and a summary of results of major efforts to date. Information is presented concerning circumferential through-wall cracked pipe in pure bending; internal circumferential surface cracked in pure bending; circumferential complex cracked pipe in noncompliant bending; circumferential complex cracked pipe in compliant bending; circumferentially cracked pipe under axial membrane loads; evaluation of the weld overlay repair method; evaluation of laboratory specimen geometry effects on J-R curves; predicting large crack growth from small specimens; effects of notch acuity on fracture mechanics specimens; development of compliant pipe test facility; and numerical-analytical assessment of cracks in welds.
