 When the American Society of Mechanical Engineers (ASME) publishes the latest version of the ASME Boiler and Pressure Vessel Codes, it will signify a monumental breakthrough in how industry addresses weld fatigue. It also marks a crowning achievement for Battelle scientist Dr. Pingsha Dong. Section VIII, Division 2 of the Code will now include Battelle’s Mesh-Insensitive Structural Stress method as an alternative means for predicting fatigue and fatigue life. The method is also known as the master S-N curve method, signifying its ability to correlate a massive amount of actual fatigue test data in a single S-N curve. The Verity method is implemented in fe-Safe—a leading fatigue software package distributed by U.K.-based Safe Technology Ltd.
