Structural Analysis on Hydroelectric Turbine Shaft Exhibiting Flaws

We were requested to performed a structural analysis and remaining life assessment of the turbine shafts on a hydroelectric plant. Inspection of the main shaft had detected linear indications at the outer surfaces of the shaft. Elastic fracture mechanics analyses indicated that the existing cracks could propagate to unacceptable levels. A solution was then designed, analyzed, and performed to extend the life of the shaft.
