Fatigue Prediction Tool Adopted by ASME Boiler and Pressure Vessel Code

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.

Because Dong’s mesh-insensitive structural stress method provides a level of predictability never before seen and can be easily applied, it was originally viewed as too good to...
