Development and application of a database of pipe fracture experiments
- Battelle, Columbus, OH (United States)
During the last 40 years, researchers worldwide have conducted thousands of pipe fracture experiments. In the last 10 to 15 years, attention has turned to understanding the behavior of circumferentially-cracked nuclear piping subjected to both internal pipe pressure and bending loads. The loading histories for these experiments ranged from the relatively simple case of quasi-static, monotonic displacement-control to the more complex cases of dynamic, cyclic loading and pipe system experiments involving simulated seismic load histories. As part of the Short Cracks in Piping and Piping Welds Research Program conducted at Battelle-Columbus and sponsored by the US Nuclear Regulatory Commission (USNRC), two databases were developed, one for axially-cracked and one for circumferentially-cracked pipe experiments. The axially-cracked and circumferentially-cracked pipe databases include the test conditions, experimental results, and material property data for approximately 220 and 700 pipe experiments, respectively. Data are included from the US, Germany, Japan, France, Italy, Canada, United Kingdom, and Finland. As part of this paper, examples of how the circumferentially-cracked pipe database can be used to validate analyses methods and possible code applications are given.
