Description
Xu and co-authors present an engineering study, published in 2025, on predicting how long giant welded shafts last under twisting and bending. Such shafts drive heavy machines, and they tend to crack where the weld meets the flange. Combined bending and twisting cut their life by 35 to 42 percent compared with bending alone, the team's tests showed. The authors built a damage-based model that tracks how harm builds up inside the metal cycle by cycle.
They tuned the model on test data and coded it into a standard engineering simulator. Its lifetime predictions landed within 5 percent of measured lives. That beat the older rule-of-thumb methods by a wide margin. A simplified version, ignoring one damage source, stayed accurate enough for high-cycle work. The model gives designers of large shafts a sharper tool for setting safe service lives.
