COLUMBUS, OH-Battelle researcher Pingsha Dong has developed a method for predicting fatigue life in welded structures that he says has the potential to save billions of dollars in the aerospace, automotive, bridge construction, shipbuilding, pipeline and offshore oil rig industries.
According to Battelle, the accuracy of Pingsha's Verity mesh-insensitive structural stress method far surpasses other modeling methods. Verity can reliably predict the fatigue life of welded structures regardless of the complexity of welded components and modeling details. As a result, Pingsha's method can eliminate the need for the expensive testing and overengineering that is often done to compensate for the uncertainties in current fatigue design practice.
