Fracture analysis of cracked elbows. Part 2: Comparison of experimental results with estimation predictions
- Battelle, Columbus, OH (United States)
Full-scale pipe fracture experiments with cracks in carbon steel and stainless steel long-radius elbow test specimens were performed at nominal pressurized water reactor conditions as part of the IPIRG-2 program. The results of these experiments were intended to provide direction and validation for the analytical methods developed to predict critical crack growth and limit loads in cracked elbows. Dynamic, cyclic pipe system experiments and companion quasi-static, monotonic experiments allowed the investigation into the complex interaction of loading conditions and system dynamics on elbow fracture behavior. Comparisons are made between existing straight pipe analysis methods, current limit load solutions for elbows, and the h-function solutions developed under the IPIRG-2 Program for cracked elbows to determine the applicability of these solutions for predicting failure stresses of cracked elbows.
