REVIEW OF DEFECT DISTRIBUTIONS FOR PROBABILISTIC STRUCTURAL INTEGRITY ASSESSMENT

摘要

The defect distribution is a particularly important parameter in the application of probabilistic defect assessment methods to the integrity assessment of welded structures. However, the subject is complex and, despite considerable research efforts in this area and the availability of a significant body of data, this defect distribution is subject to considerable variability and uncertainty. This paper reviews the data in the literature, providing a status review of defect distributions and the identification of areas requiring further investigation, with a view to assisting with the future development of probabilistic defect assessment methods.
