Part 1: Fatigue Strength Reduction and Stress Concentration Factors for Welds in Pressure Vessels and Piping: Interpretive Review of Weld Fatigue-Strength-Reduction and Stress-Concentration Factors
Summary
The objectives of this report are to (1) clarify the current procedures for determining values of fatigue-strength-reduction factors (FSRFs), (2) collect relevant published data on weld-joint FSRFs, (3) interpret existing data on weld-joint FSRFs, (4) facilitate the development of a future database of FSRFs for weld joints, and (5) facilitate the development of a standard procedure for determining the values of FSRFs for weld joints.The main focus of this report is on weld joints in Class 1 nuclear pressure vessels and piping. However, relevant fatigue data on similar weld joints for other applications, such as bridges and offshore structures, also are reviewed and interpreted.
