Researcher proposes using mesh-insensitive structural stress methods to predict bridge fatigue
Posted by Scott Melnick on October 11, 2007 at 1:30 PM.

Pingsha Dong, a Battelle scientist, has developed a new method for predicting fatigue and fatigue life. The method, known both as the Verity mesh-insensitive structural stress method and the master S-N curve methodology, has been adopted by the American Society of Mechanical Engineers as an alternative method in their boiler and pressure vessel codes.

 

However, Dong noted that the the mesh-insensitive structural stress method is directly applicable to fatigue design and life prediction of steel bridge structures, as well as remaining life assessment for aging bridges. “Recently published full-scale fatigue data for steel bridges and signal masts, funded by the DOT [Department of Transportation] and various states’ DOTs, has been predicted by our method as stipulated in the 2007 ASME Code.”
